MOUNTING
M-Series Gas Flow Meters have holes on the bottom for mounting to flat panels. See pages 49-62.
M-Series Meters can usually be mounted in any position.
No straight runs of pipe are required upstream or downstream of the meter.
PLUMBING
Your meter is shipped with plastic plugs fitted in the port openings. To lessen the chance of contaminating the flow stream do not remove these plugs until you are ready to install the device.
Make sure that the gas will flow in the direction indicated by the flow arrow.
Standard M-Series Gas Flow Meters have female inlet and outlet port connections. Welded VCR and other specialty fittings may have male ports.
The inlet and outlet port sizes (process connections) for different flow ranges are shown on pages 49-62.
Meters with M5 (10-32) ports have O-ring face seals and require no sealant or tape. Do not use tape with welded or O-ring fittings.
For non M5 (10-32) ports use thread sealing Teflon® tape to prevent leakage around the port threads.
Do not wrap the first two threads. This will minimize the possibility of getting tape into the flow stream and flow body.
Do not use pipe dopes or sealants on the process connections as these compounds can cause permanent damage to the meter should they get into the flow stream.
6
We recommend the use of in-line sintered filters to prevent large particulates from entering the measurement head of the instrument.
Suggested maximum particulate sizes are as follows:
5 microns for units with FS flow ranges of 0-1 sccm or less.
20 microns for units with FS flow ranges between 0-2 sccm and 0-1 slpm.
50 microns for units with FS flow ranges of 0-1 slpm or more.
PRESSURE
Maximum operating line pressure for M-Series units is 145 psig (1 MPa).
If the line pressure is higher than 145 psig (1 MPa), use a pressure regulator upstream from the flow meter to reduce the pressure to 145 psig (1 MPa) or less.
Maximum operating line pressure for MW-Series units is 50 psig.
Exceeding the maximum specified line pressure may cause permanent damage to the solid-state differential pressure sensor.
Do Not subject an M-Series Differential Pressure sensor to upstream-downstream pressure differentials exceeding 75 PSID.
Do Not subject a MW-Series Differential Pressure sensor to upstream-downstream pressure differentials exceeding 15 PSID.
While high static pressure will typically not damage the dp sensor, sudden pressure “spikes” can result in complete failure of the sensor.
A common cause of this problem is instantaneous application of high-pressure gas as from a snap acting solenoid valve either upstream or downstream of the meter. If you suspect that your pressure sensor is damaged please discontinue use of the meter and contact Apex.

POWER AND SIGNAL CONNECTIONS
Power can be supplied to your meter through either the power jack (power jack not available on CSA/ATEX approved devices) or the 8 pin Mini-DIN connector.
An AC to DC adapter which converts line AC power to DC voltage and current as specifi ed below is required to use the power jack.
Meters require a 7-30 Vdc power supply with a 2.1 mm female positi ve center plug capable of supplying at least 100mA.
Note: 4-20mA analog output requires at least 15 Vdc.

It is common to mistake Pin 2 (labeled 5.12 Vdc Output) as the standard 0-5 Vdc
analog output signal. In fact Pin 2 is normally a constant 5.12 Vdc that refl ects the system bus voltage and can be used as a source for the set-point signal.
For 6 Pin Locking Industrial Connector and DB15 Pin-outs, see pages 64 to 70.

INPUT SIGNALS
Analog Input Signal
Apply analog input to Pin 4 as shown on page 8.
For 6 Pin Locking Connector and DB15 Pin-outs, see pages 64 to 70.
Standard 0-5 Vdc is the standard analog input signal. Apply the 0-5 Vdc input signal to pin 4, with common ground on pin 8.
Opti onal 0-10 Vdc: If specifi ed at ti me of order, a 0-10 Vdc input signal can be applied to pin 4, with common ground on pin 8.
Opti onal 4-20 mA: If specifi ed at ti me of order, a 4-20 mA input signal can be applied to pin 4, with common ground on pin 8.
NOTE: This is a current sinking device. The receiving circuit is essenti ally a
250 ohm resistor to ground.
NOTE: 4-20 mA output requires at least 15 Vdc power input.

OUTPUT SIGNALS
RS-232 / RS-485 Digital Output Signal
To use the RS-232 or RS-485 output signal, it is necessary to connect the RS-232
/ RS-485 Output Signal (Pin 5), the RS-232 / RS-485 Input Signal (Pin 3), and
Ground (Pin 8) to your computer serial port as shown on page 8. (See page 25 for details on accessing RS-232 / RS-485 output.)
Standard Voltage (0-5 Vdc) Output Signal
M-Series fl ow meters equipped with a 0-5 Vdc (opti onal 0-10 Vdc) will have this output signal available on Pin 6. This output is generally available in additi on to other opti onally ordered outputs. This voltage is usually in the range of 0.010
Vdc for zero fl ow and 5.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.
Opti onal 0-10 Vdc Output Signal
If your meter was ordered with a 0-10 Vdc output signal, it will be available on
Pin 6. (See the Calibrati on Data Sheet that shipped with your meter to determine which output signals were ordered.) This voltage is usually in the range of 0.010
Vdc for zero fl ow and 10.0 Vdc for full-scale fl ow. The output voltage is linear over the enti re range. Ground for this signal is common on Pin 8.
Opti onal Current (4-20 mA) Output Signal
If your meter was ordered with a 4-20 mA current output signal, it will be available on Pin 1. (See the Calibrati on Data Sheet that shipped with your meter to determine which output signals were ordered.) The current signal is 4 mA at
0 fl ow and 20 mA at the meter’s full scale fl ow. The output current is linear over the enti re range. Ground for this signal is common on Pin 8. (Current output units require 15-30Vdc power.)
Opti onal 2nd Analog Output Signal
You may specify an opti onal 2nd analog output on Pin 2 at ti me of order. (See the Calibrati on Data Sheet that shipped with your meter to determine which output signals were ordered.) This output may be a 0-5 Vdc, 0-10 Vdc, or
4-20 mA analog signal that can represent any measured parameter. With this opti onal output, a meter could output the mass fl ow rate (0-5 Vdc on pin 6) and the absolute pressure (0-5 Vdc on pin 2).
If your device is CSA/ATEX approved or equipped with the opti onal six pin industrial connector, please contact Apex.

To select a temperature scale, use the UP and DOWN buttons to position the arrow in front of the desired scale.
Press SET to record your selection and return to the MAIN display. The selected temperature scale will be displayed on the screen.
Tare: Pushing the TARE V button tares the flow meter and provides it with a reference point for zero flow. This is an important step in obtaining accurate measurements. It is best to zero the flow meter each time it is powered up. If the flow reading varies significantly from zero after an initial tare, give the unit a minute or so to warm up and re-zero it.
If possible, zero the unit near the expected operating pressure by positively blocking the flow downstream of the flow meter prior to pushing the TARE button.
Zeroing the unit while there is any flow will directly affect the accuracy
by providing a false zero point. If in doubt about whether a zero flow condition exists, remove the unit from the line and positively block both ports before pressing the TARE button. If the unit reads a significant negative value
15
when removed from the line and blocked, it was given a false zero. It is bett er to zero the unit at atmospheric pressure and a confi rmed no fl ow conditi on than to give it a false zero under line pressure.
Volumetric Flow Rate: This parameter is located in the lower left of the display.
It is moved to the primary display by pushing the butt on below CCM in this example. Your display may show a diff erent unit of measure.
Mass Flow Rate: The mass fl ow rate is the volumetric fl ow rate corrected to a standard temperature and pressure (typically 14.696 psia and 25 °C).
This parameter is located in the lower middle of the display. It can be moved to the primary display by pushing the butt on below SCCM in this example. Your display may show a diff erent unit of measure preceded by the lett er S.
To get an accurate volumetric or mass fl ow rate, the gas being measured must be selected. See Gas Select, page 18.
MENU: Pressing MENU switches the screen to the Select Menu display.
Flashing Error Message: An error message (MOV = mass overrange,
VOV = volumetric overrange, POV = pressure overrange, TOV = temperature overrange) fl ashes when a measured parameter exceeds the range of the sensor. When any item fl ashes, neither the fl ashing parameter nor the mass fl ow measurement is accurate. Reducing the value of the fl ashing parameter to within specifi ed limits will return the unit to normal operati on and accuracy.
If the unit does not return to normal operati on contact Apex.

Pressure Averaging and Flow Averaging may be useful to make it easier to read and interpret rapidly fluctuating pressures and flows. Pressure and flow averaging can be adjusted between 1
(no averaging) and 256 (maximum averaging).
These are geometric running averages where the number between 1 and 256 can be considered roughly equivalent to the response time constant in milliseconds.
This can be effective at “smoothing” high frequency process oscillations such as those caused by diaphragm pumps.

RS-232 / RS-485 Output and Input
Configuring HyperTerminal®:
1. Open your HyperTerminal® RS-232 / RS-485 terminal program (installed under the “Accessories” menu on all Microsoft Windows® operating systems).
2. Select “Properties” from the file menu.
3. Click on the “Configure” button under the “Connect To” tab. Be sure the program is set for: 19,200 baud (or matches the baud rate selected in the
RS-232 / RS-485 communications menu on the meter) and an 8-N-1-None (8
Data Bits, No Parity, 1 Stop Bit, and no Flow Control) protocol.
4. Under the “Settings” tab, make sure the Terminal Emulation is set to ANSI or Auto Detect.
5. Click on the “ASCII Setup” button and be sure the “Send Line Ends with Line
Feeds” box is not checked and the “Echo Typed Characters Locally” box and the “Append Line Feeds to Incoming Lines” boxes are checked. Those settings not mentioned here are normally okay in the default position.
6. Save the settings, close HyperTerminal® and reopen it.
Streaming Mode (RS-485 units do not have a streaming mode)
In the default Polling Mode, the screen should be blank except the blinking cursor.
In order to get the data streaming to the screen, hit the “Enter” key several times to clear any extraneous information. Type “*@=@” followed by “Enter” (or using the RS-232 / RS-485 communication select menu, select @ as identifier and exit the screen). If data still does not appear, check all the connections and COM port assignments.
Streaming Mode – Advanced
The streaming data rate is controlled by register 91. The recommended default rate of data provision is once every 50 milliseconds and this is suitable for most purposes.
If a slower or faster streaming data rate is desired, register 91 can be changed to a value from 1 millisecond to 65535 milliseconds, or slightly over once every minute.
Below approximately 40 milliseconds, data provision will be dependent upon how many parameters are selected. Fewer data parameters can be streamed more quickly than more. It is left to the user to balance streaming speed with number of parameters streamed.
To read register 91, type “*r91” followed by “Enter”.
To modify register 91, type “*w91=X”, where X is a positive integer from 1 to
65535, followed by “Enter”.
To return to the recommended factory default streaming speed, type “*w91= 50”.
25
Tareing via RS-232 / RS-485:
Tare –Tareing (or zeroing) the flow meter provides it with a reference point for zero flow. This is a simple but important step in obtaining accurate measurements.
It is good practice to “zero” the flow meter each time it is powered up. A unit may be Tared by following the instructions on page 10 or it may be Tared via RS-232
/ RS-485 input.
To send a Tare command via RS-232 / RS-485, enter the following strings:
In Polling Mode: Address$$V<Enter> (e.g. B$$V<Enter>)
Changing From Streaming to Polling Mode:
When the meter is in the Streaming Mode (RS-485 units do not have a streaming
mode), the screen is updated approximately 10-60 times per second (depending on the amount of data on each line) so that the user sees the data essentially in real time. It is sometimes desirable, and necessary when using more than one unit on a single RS-232 line, to be able to poll the unit.
In Polling Mode the unit measures the flow normally, but only sends a line of data when it is “polled”. Each unit can be given its own unique identifier or address.
Unless otherwise specified each unit is shipped with a default address of capital
A. Other valid addresses are B thru Z.
Once you have established communication with the unit and have a stream of information filling your screen:
1. Type *@=A followed by “Enter” (or using the RS-232 / RS-485 communication select menu, select A as identifier and exit the screen) to stop the streaming mode of information. Note that the flow of information will not stop while you are typing and you will not be able to read what you have typed. Also, the unit does not accept a backspace or delete in the line so it must be typed correctly. If in doubt, simply hit enter and start again. If the unit does not get exactly what it is expecting, it will ignore it. If the line has been typed correctly, the data will stop.
2. You may now poll the unit by typing A followed by “Enter”. This does an instantaneous poll of unit A and returns the values once. You may type A
“Enter” as many times as you like. Alternately you could resume streaming mode by typing *@=@ followed by “Enter”. Repeat step 1 to remove the unit from the streaming mode.
3. To assign the unit a new address, type *@=New Address, e.g. *@=B. Care should be taken not to assign an address to a unit if more than one unit is on the RS-232 / RS-485 line as all of the addresses will be reassigned. Instead, each should be individually attached to the RS-232 / RS-485 line, given an address, and taken off. After each unit has been given a unique address, they can all be put back on the same line and polled individually.
26
Gas Select – The selected gas can be changed via RS-232 / RS-485 input. To change the selected gas, enter the following commands:
In Polling Mode: Address$$#<Enter> (e.g. B$$#<Enter>)
Where # is the number of the gas selected from the table below. Note that this also corresponds to the gas select menu on the flow controller screen (the
Standard gas category is shown in the example below):

Collecting Data:
The RS-232 / RS-485 output updates to the screen many times per second.
Very short-term events can be captured simply by disconnecting (there are two telephone symbol icons at the top of the HyperTerminal® screen for disconnecting and connecting) immediately after the event in question. The scroll bar can be driven up to the event and all of the data associated with the event can be selected, copied, and pasted into Microsoft® Excel® or other spreadsheet program as described below.
For longer term data, it is useful to capture the data in a text file. With the desired data streaming to the screen, select “Capture Text” from the Transfer Menu.
Type in the path and file name you wish to use. Push the start button. When the data collection period is complete, simply select “Capture Text” from the Transfer
Menu and select “Stop” from the sub-menu that appears.
Data that is selected and copied, either directly from HyperTerminal® or from a text file can be pasted directly into Excel®. When the data is pasted it will all be in the selected column. Select “Text to Columns...” under the Data menu in
Excel® and a Text to Columns Wizard (dialog box) will appear. Make sure that
“Fixed Width” is selected under Original Data Type in the first dialog box and click “Next”. In the second dialog box, set the column widths as desired, but the default is usually acceptable. Click on “Next” again. In the third dialog box, make sure the column data format is set to “General”, and click “Finish”. This separates the data into columns for manipulation and removes symbols such as the plus signs from the numbers. Once the data is in this format, it can be graphed or manipulated as desired.
For extended term data capture see: “Sending a Simple Script to HyperTerminal®” on page 30.

Data Format:
The data stream on the screen represents the flow parameters of the main mode in the units shown on the display.
For mass flow meters, there are five columns of data representing pressure, temperature, volumetric flow, mass flow and the selected gas. The first column is absolute pressure (normally in psia), the second column is temperature (normally in °C), the third column is volumetric flow rate (in the units specified at time of order and shown on the display), and the fourth column is mass flow (also in the units specified at time of order and shown on the display). For instance, if the meter was ordered in units of scfm, the display on the meter would read 2.004 scfm and the last two columns of the output below would represent volumetric flow and mass flow in cfm and scfm respectively.

Sending a Simple Script File to HyperTerminal®
It is sometimes desirable to capture data for an extended period of time. Standard streaming mode information is useful for short term events, however, when capturing data for an extended period of time, the amount of data and thus the file size can become too large very quickly. Without any special programming skills, you can use HyperTerminal® and a text editing program such as Microsoft®
Word® to capture text at defined intervals.
1. Open your text editing program, MS Word for example.
2. Set the cap lock on so that you are typing in capital letters.
3. Beginning at the top of the page, type A<Enter> repeatedly. If you’re using MS
Word, you can tell how many lines you have by the line count at the bottom of the screen. The number of lines will correspond to the total number of times the flow device will be polled, and thus the total number of lines of data it will produce.
For example: A
A
A
A
A
A will get a total of six lines of data from the flow meter, but you can enter as many as you like.
The time between each line will be set in HyperTerminal.
4. When you have as many lines as you wish, go to the File menu and select save.
In the save dialog box, enter a path and file name as desired and in the “Save as
Type” box, select the plain text (.txt) option. It is important that it be saved as a generic text file for HyperTerminal to work with it.
5. Click Save.
6. A file conversion box will appear. In the “End Lines With” drop down box, select
CR Only. Everything else can be left as default.
7. Click O.K.
8. You have now created a “script” file to send to HyperTerminal. Close the file and exit the text editing program.
9. Open HyperTerminal and establish communication with your flow device as outlined in the manual.
10. Set the flow device to Polling Mode as described in the manual. Each time you type A<Enter>, the meter should return one line of data to the screen.
11. Go to the File menu in HyperTerminal and select “Properties”.
12. Select the “Settings” tab.
13. Click on the “ASCII Setup” button.
30
14. The “Line Delay” box is defaulted to 0 milliseconds. This is where you will tell the program how often to read a line from the script file you’ve created. 1000 milliseconds is one second, so if you want a line of data every 30 seconds, you would enter 30000 into the box. If you want a line every 5 minutes, you would enter 300000 into the box.
15. When you have entered the value you want, click on OK and OK in the
Properties dialog box.
16. Go the Transfer menu and select “Send Text File…” (NOT Send File…).
17. Browse and select the text “script” file you created.
18. Click Open.
19. The program will begin “executing” your script file, reading one line at a time with the line delay you specified and the flow device will respond by sending one line of data for each poll it receives, when it receives it.
You can also capture the data to another file as described in the manual under
“Collecting Data”. You will be simultaneously sending it a script file and capturing the output to a separate file for analysis.
Operating Principle
All M-Series Gas Flow Meters (and MC Series Gas Flow Controllers) are based on the accurate measurement of volumetric flow. The volumetric flow rate is determined by creating a pressure drop across a unique internal restriction, known as a Laminar
Flow Element (LFE), and measuring differential pressure across it. The restriction is designed so that the gas molecules are forced to move in parallel paths along the entire length of the passage; hence laminar (streamline) flow is established for the entire range of operation of the device. Unlike other flow measuring devices, in laminar flow meters the relationship between pressure drop and flow is linear.
Please visit the Apex web site for a detailed explanation this principle.
http://www.Apex.com/technical-information/theory-of-operation/
STANDARD GAS DATA TABLES: Those of you who have older Apex products may notice small discrepancies between the gas property tables of your old and new units. Apex has incorporated the latest data sets from NIST (including their REFPROP 9 data where available) in our products’ built-in gas property models. Be aware that the calibrators that you may be using may be checking against older data sets such as the widely distributed Air Liquide data. This may generate apparent calibration discrepancies of up to 0.6% of reading on well behaved gases and as much as 3% of reading on some gases such as propane and butane, unless the standard was directly calibrated on the gas in question.
As the older standards are phased out, this difference in readings will cease to be a problem. If you see a difference between the Apex meter and your in-house standard, in addition to calling Apex, call the manufacturer of your standard for clarification as to which data set they used in their calibration. This comparison will in all likelihood resolve the problem.

TROUBLESHOOTING
Display does not come on or is weak.
Check power and ground connections. Please reference the technical specifications (pages 49-62) to assure you have the proper power for your model.
Flow reading is approximately fixed either near zero or near full scale regardless of actual line flow.
Differential pressure sensor may be damaged. Avoid installations that can subject the sensor to excessive pressure differentials (see page 7). A common cause of this problem is instantaneous application of high-pressure gas as from a snap acting solenoid valve upstream of the meter. If you suspect that your pressure sensor is damaged please discontinue use of the meter and contact Apex.
Displayed mass flow, volumetric flow, pressure or temperature is flashing and message MOV, VOV, POV or TOV is displayed:
Our flow meters and controllers display an error message (MOV = mass overrange, VOV = volumetric overrange, POV = pressure overrange, TOV = temperature overrange) when a measured parameter exceeds the range of the sensors in the device. When any item flashes on the display, neither the flashing parameter nor the mass flow measurement is accurate. Reducing the value of the flashing parameter to within specified limits will return the unit to normal operation and accuracy. If the unit does not return to normal contact Apex.
Meter reads negative flow when there is a confirmed no flow condition.
This is an indication of an improper tare. If the meter is tared while there is flow, that flow is accepted as zero flow. When an actual zero flow condition exists, the meter will read a negative flow. Simply re-tare at the confirmed zero flow condition. Also note that while the meter is intended for positive flow, it will read negative flow with reasonable accuracy, but not to the full scale flow rate
(it is not calibrated for bi-directional flow) and no damage will result.
Meter does not agree with another meter I have in line.
Volumetric meters are affected by pressure drops. Volumetric flow meters should not be compared to mass flow meters. Mass flow meters can be compared against one another provided there are no leaks between the two meters and they are set to the same standard temperature and pressure. Both meters must also be calibrated (or set) for the gas being measured. M-Series mass flow meters are normally set to Standard Temperature and Pressure conditions of 25° C and 14.696 psia. Note: it is possible to special order meters with a customer specified set of standard conditions. The calibration sheet provided with each meter lists its standard conditions.
When performing this comparison it is best to use the smallest transition possible between the two devices. Using small transitions will minimize lag and dead volume.
40
Flow flutters or is jumpy.
The meters are very fast and will pick up any actual flow fluctuations such as from a diaphragm pump, etc. Also, inspect the inside of the upstream connection for debris such a Teflon tape shreds.
Note: M-Series meters feature a programmable geometric running average (GRA) that can aid in allowing a rapidly fluctuating flow to be read (see “Pressure Averaging” and
“Flow Averaging” page 20).
The output signal is lower than the reading at the display.
This can occur if the output signal is measured some distance from the meter, as voltage drops in the wires increase with distance. Using heavier gauge wires, especially in the ground wire, can reduce this effect.
RS-232 / RS-485 Serial Communications is not responding.
Check that your meter is powered and connected properly. Be sure that the port on the computer to which the meter is connected is active. Confirm that the port settings are correct per the RS-232 instructions in this manual (Check the RS-232 / RS-485 communications select screen for current meter readings).
Close Hyperterminal® and reopen it. Reboot your PC. See pages 10, 11 and 25 for more information on RS-232 / RS-485 signals and communications.
Slower response than specified.
M-Series Meters feature a programmable Geometric Running Average
(GRA). Depending on the full scale range of the meter, it may have the GRA set to enhance the stability/readability of the display, which would result in slower perceived response time. Please see “Pressure Averaging” and “Flow
Averaging” on page 20.
Jumps to zero at low flow.
M-Series Meters feature a programmable zero deadband. The factory setting is usually 0.5% of full scale. This can be adjusted between NONE and 3.2% of full scale. See page 20.
Discrepancies between old and new units.
Please see “Standard Gas Data Tables” explanation on page 31.

Maintenance and Recalibration
General: M-Series Flow Meters require minimal maintenance. They have no moving parts. The single most important thing that affects the life and accuracy of these devices is the quality of the gas being measured. The meter is designed to measure CLEAN, DRY, NON-CORROSIVE gases.
Moisture, oil and other contaminants can affect the laminar flow elements.
We recommend the use of in-line sintered filters to prevent large particulates from entering the measurement head of the instrument. Suggested maximum particulate sizes are as follows:
5 microns for units with FS flow ranges of 0-1 sccm or less.
20 microns for units with FS flow ranges between 0-2 sccm and 0-1 slpm.
50 microns for units with FS flow ranges of 0-1 slpm or more.
Recalibration: The recommended period for recalibration is once every year.
A label located on the back of the meter lists the most recent calibration date.
The meter should be returned to the factory for recalibration within one year from the listed date. Before calling to schedule a recalibration, please note the serial number on the back of the meter. The Serial Number, Model Number, and
Date of Manufacture are also available on the Model Info display (page 24).
Cleaning: M-Series Flow Meters require no periodic cleaning. If necessary, the outside of the meter can be cleaned with a soft dry cloth. Avoid excess moisture or solvents.

Rollover – The customer can also specify at the time of order what the totalizer is to do when the maximum count is reached. The following options may be specified:
No Rollover – When the counter reaches the maximum count it stops counting until the counter is cleared.
Rollover – When the counter reaches the maximum count it automatically rolls over to zero and continues counting until the counter is cleared.
Rollover with Notification – When the counter reaches the maximum count it automatically rolls over to zero, displays an overflow error, and continues counting until the counter is cleared.
TOTAL MASS: The counter can have as many as seven digits. At the time of order, the customer must specify the range. This directly affects the maximum count. For instance, if a range of 1/100ths of a liter is specified on a meter which is totalizing in liters, the maximum count would be 99999.99 liters. If the same unit were specified with a 1 liter range, the maximum count would be 9999999 liters.
ELAPSED TIME: The small numbers below the mass total show the elapsed time since the last reset in hours, minutes and seconds. The maximum measurable elapsed time is 9999 hours 59 minutes 59 seconds. The hours count resets when

Apex Portable Meters and Gauges
Apex Rechargeable Flow Meters and Pressure Gauges use a Li-Ion 3.7V cell located in the top secti on of the device. The Li-Ion cell must not be removed.
Normal batt ery life of a fully-charged cell is 18 hours with a monochrome display or
5 hours with a TFT color display, when the backlight is set to 10. Dimming the backlight will increase batt ery life.
The batt ery can be charged through either the micro-USB port or the mini-DIN connector.
When the device is connected to external power it will functi on normally while the batt ery is charging. Note: If the batt ery has no charge, a charge ti me of one minute will be required before the unit can be turned on. Charge rates will be fastest through the micro-USB port using the included power supply or equivalent. The device will charge fastest when it is turned off .
Recharge Time: 3.5 hours with 2A USB supply. The micro-USB port is for charging purposes only.
The green/red indicator LED on top of the device will light up green to indicate that the unit is charging. The green LED will turn off when the batt ery is charged and the power switch is turned to “I” for ON.
The indicator LED fl ashes red when the device has about 1 hour of batt ery life remaining. The
LED will fl ash red at a faster rate when the device has about 15 minutes of batt ery life remaining.
It is highly recommended that the device be charged immediately. When the batt ery charge runs out, the display contrast will turn to 0 and device performance is no longer guaranteed.
Output signals from the meter are passed through the mini-DIN connector on top of the device. Rechargeable batt ery units do not support 0-10V analog output.
Receiver resistance must be below 250Ω.
Turn the power switch on top of the device to “O” for OFF when it is not in use.
Warning: If the device is left ON unti l the batt ery can no longer power it, the charge indicator will fall out of sync with the actual charge. The device can be re-synced by fully charging the batt ery once.

Accessory: Multi -Drop Box
The Multi -Drop Box makes it convenient to wire multi ple fl ow and/or pressure devices to a single RS-232 or RS-485 port. Now available with a USB interface!
The Multi -Drop Box has nine 8 pin mini-DIN ports available. The ports are to be used with a standard double ended 8 pin mini-DIN (DC-62) style cable going from the box to each fl ow or pressure device.
A single DB9 D-SUB type connector (COM PORT) connects, using the included cable, to the serial connector on a PC or laptop.
All of the fl ow and/or pressure devices are powered via a terminal block on the front of the box.
If more than nine devices will be required, additi onal Multi -Drop Boxes can be daisy chained together with a double ended 8 pin mini-DIN cable plugged into any receptacle on both boxes.
Multi -Drop Box Power Supply for Large Valve Controllers: The PS24VHC
(Power Supply 24Vdc High Current) is a 6.5Amp 24Vdc power supply designed for running multi ple large controllers on a Multi -Drop Box.
The 6.5Amp power supply can run as many as 8 large valve controllers, which makes it ideal for the Multi -Drop Box and multi ple large valve (or small valve / large valve combinati on) controllers on a Multi -Drop Box.
