GENERAL INFORMATION FTB700 SERIES INSTRUCTIONS

This unique system of 3" to 8" turbine meters uses just one moving part, a precision helical rotor. Rotation of the rotor is electronically detected and processed. The high-quality jewel bearings and shafts minimize friction while providing long life in non-lubricating fluids. The entire rotor assembly can be easily removed for field service without removing the meter from the pipe.

FTB700 meters can be ordered with various output options. The basic model comes with pulse output only. An electronic display is available on the DPF144-P/DPF144-W model to display flow rate and total (resettable or non-resettable), and provide a programmable pulse or 4-20 mA output. The controls/displays can be mounted on the meter or remotely mounted on a wall or panel up to 2,000 feet away. FTB700 meters are compatible for use with other remote-mount Omega displays and controls as well.

FTB700 bodies are fabricated from Schedule 80 PVC fittings or from stainless steel tubing. The turbine insert on the stainless steel meters is machined from a stainless steel casting. The PVC turbine insert is machined from a solid piece of PVC. Turbine rotors on all models are PVDF.

Flanges

Flange

150 lb drilling

Flanges. For stainless steel meters, standard flanges are 150 lb. ANSI drilling. PVC meters can be installed with optional flanges according to pipe manufacturer’s recommendations. For PVC a bolt torque of 20-30 ftlb for 3” and 4” flanges, and 35-50 ft-lb for 6” flanges is recommended.

Either partial or full-face gaskets can be used. Tighten the bolts evenly. Use care to prevent a misaligned gasket from entering the flow stream.

Position. The FTB700 Series are all-position meters, operable in a vertical or horizontal position, with the meter insert in any radial position. A horizontal position is preferred if there is a risk of air becoming trapped due to constant low flows. Operating the meter in partially-filled pipe will result in inaccuracies.

Turbine Insert Removal and Installation.

CAUTION: First remove all pressure from the line. Then remove the screws or bolts that hold the insert in place and tug gently until the insert comes free. A twisting motion can help to loosen the O-ring seal. Reverse the procedure to reinstall, after coating the O-ring with lubricant (plastic compatible in the PVC model). Do not overtighten.

Rotor and Shaft Replacement. Examine the rotor to determine if bearings or shaft are damaged or excessively worn. The rotor should spin smoothly and freely, with no visible wobble. Back and forth play should be very minor, less than 1/64”. If it is necessary to replace the rotor or shafts, first back out both shafts with a small blade screwdriver. The rotor will come free as soon as the shaft ends come free of the rotor bearings. Reverse the procedure to reinstall. Note: Do not overtighten the shaft

screws. Check to be sure that a small amount of free play between the shaft ends and the bearings remains.

Sensor Output

For operating instructions for the various electronic modules, consult the manual for the specific module, included with the meter at purchase.

Sensor Replacement. This is rarely necessary. However, certain electrical conditions can damage the sensor. To replace it, first remove the electronics module. Disconnect the sensor leads from the electronics module terminals and remove the threaded plug over the sensor. Finally, remove the sensor by pulling on the sensor leads. A gentle tug should be sufficient. Reverse the process to replace the sensor.

FTB700-T

Blind Analog Transmitter Instructions

FTB700-T INSTRUCTIONS

The Omega FTB700-T is a blind (non-indicating) 4-20 mA transmitter. It accepts a pulse frequency input from the flow sensor, and converts this input into a continuous analog output signal. Power for the transmitter is taken from the current loop itself, so only two wires are required. The digital design makes it possible to span the unit in the field without tools. The frequency at which 20 mA is desired is entered on a set of rotary switches, and an internal microcontroller automatically scales all other values accordingly. An additional benefit of the microcontroller is its ability to average inputs, for smoothing of the output signal. The degree of averaging can be selected in the field, from 2 to 16 seconds.

For maximum environmental protection, the electronic components are encased in a special semi-flexible urethane potting material. The housing is cast from aluminum and fuse-coated. The clamshell housing is provided with mounting feet or remote mounting.

The FTB700-T will operate on a relatively wide range of current loop voltages, 24 to 36 Vdc. Lower voltages limit the load that can be applied to the loop without distortion of the signal. (See Load/Supply chart if there is a question regarding voltage vs. load.) A built-in power regulator supplies the appropriate power to the flow sensor.

Typical applications for this transmitter are telemetry (or SCADA), distributed control systems, programmable controllers, data logging, and chart recording.

Installation

The upper portion of the housing must be removed to make connections. Use a standard hex wrench (5/32” or 4 mm) to loosen the screws, then remove the upper half. The connections are made to terminal blocks in the upper half, which contains the potted electronics.

Consult the FTB700-T Connections diagram before connecting to the current loop and flow sensor. Be careful to follow the color coding of the flow sensor wires in order to establish the correct polarity. Incorrect polarity can damage the sensor.

SETTINGS AND CALIBRATION FTB700-T INSTRUCTIONS

Setting Frequency

The FTB700-T converts a train of off/on pulses from the flow sensor into a continuous milliAmp signal that ranges from 4 mA at zero flow to 20 mA at the desired maximum flow. The desired maximum is determined by the user and entered as a frequency as follows:

1. Decide what flow rate should represent the top of the scale. This is ordinarily the maximum expected flow, or a value just above it, in gallons per minute.

2. Locate the K-factor of the flow sensor (found on the meter or fitting. The K-factor is the number of pulses the flow sensor produces per gallon of flow.

3. Calculate frequency, using this formula:

Setting Averaging Time

For most applications, this step can be ignored, as the standard setting will work fine. However, when a particularly steady output signal is desired, or in large pipe, a larger averaging period may be desirable. Note however that the averaging period requires a tradeoff, since a longer averaging period implies a slower response time. If steady signal is more important than fast response, increase the averaging time as desired. See the diagram below for the switch positions and their corresponding times.

Power

Setting Frequency Example

1. In an installation with an estimated maximum flow rate of about 150 GPM, a flow rate of 170

GPM is selected as the full-scale maximum, the flow at which the current loop will register 20 mA.

2. In this example, the K-factor (found on the meter or fitting, or in the manual) is “K =

54.50”.

3. Calculate the frequency as:

54.50 x 170 = 154.42

60

4. Rounding to one decimal point, enter 154.4 on the rotary switches by turning the rotary switch pointers to the desired digits.

Checking Calibration

Normally it should not be necessary to check calibration, since the digital design of this unit virtually eliminates drift.

However, there are two types of calibration check that can be performed. Look at the diagram below to locate the 4 and 20 mA force switches. To force the 4 mA output, put its switch in the up position. Check the current output at the Power terminals, and if necessary trim to 4.00 mA using the appropriate trimpot. Return the switch to the down position, and repeat the process with the 20 mA switch.
