Section 1: Description and Specifications

1.1

Features and Applications

COMPLETE SYSTEM includes single or dual input analyzer, sensor(s), and debubbler assembly

CHOOSE U.S. EPA METHOD 180.1 or ISO METHOD 7027 compliant sensors

RESOLUTION 0.001 NTU

FULL FEATURED ANALYZER with fully scalable analog outputs and fully programmable alarms with interval timers

INTUITIVE, USER-FRIENDLY MENU in seven languages makes setup and calibration easy

The Clarity II turbidimeter is intended for the determination of turbidity in water. Low stray light, high stability, efficient bubble rejection, and a display resolution of 0.001 NTU make

Clarity II ideal for monitoring the turbidity of filtered drinking water. The Clarity II turbidimeter can be used in applications other than drinking water treatment. Examples are monitoring wastewater discharges, condensate returns, and clarifiers.

Both USEPA 180.1 and ISO 7027-compliant sensors are available. USEPA 180.1 sensors use a visible light source. ISO 7027 sensors use a near infrared LED. For regulatory monitoring in the

United States, USEPA 180.1 sensors must be used. Regulatory agencies in other countries may have different requirements.

The Clarity II turbidimeter consists of an analyzer, which accepts either one or two sensors, the sensors themselves, and a debubbler/measuring chamber and cable for each sensor. The cable plugs into the sensor and the analyzer, making setup fast and easy. Sensors can be located as far as 50 ft (15.2 m) away from the analyzer.

The Clarity II turbidimeter incorporates the popular and easy to use 56 analyzer. Menu flows and prompts are so intuitive that a manual is practically not needed. Analog outputs are fully scalable. Alarms are fully programmable for high/low logic and dead band. To simplify programming, the analyzer automatically detects whether an EPA 180.1 or ISO 7027 sensor is being used.

Clarity II is available in an optional configuration in which the analyzer, sensor(s), and debubbling flow cell(s) are mounted on a single back plate. The sensor cables are pre-wired to the analyzer, so setup is exceptionally fast and easy. All the user does is mount the unit on a wall, bring in power and sample, and provide a drain. To order this option, consult the factory.

Installation – Debubbler Assembly

See Figure 2-3 for installation.

Connect the sample line to the inlet fitting. The fitting accepts 1/4-inch OD tubing. See Section

2.6 for recommended installation of the sample port.

Attach a piece of 3/8 inch ID soft tubing to the drain fitting. The debubbler must drain to atmosphere.

NOTE:

During operation, the debubbler is under pressure. A 0.040 inch (1 mm) orifice in the outlet provides the pressure. Back pressure helps prevent outgassing, which can lead to bubbles accumulating on the sensor face resulting in erroneous readings. DO NOT

EXCEED 30 psig (308 kPa abs) inlet pressure.

WARNING

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process temperature is lowered to a safe level!

The amount of pressure in the debubbler can be estimated from the flow rate. See Table 2-1.

To control and monitor sample flow, a valved rotameter with fittings is available (PN 24103-00).

Attach the rotameter to the debubbler outlet. The rotameter can also be used to increase back pressure on the debubbler if additional pressure is needed to prevent outgassing.

Section 3.0 Wiring

3.1

3.1.1.

General

The T56 is easy to wire. It includes removable connectors and slide-out signal input boards. The front panel is hinged at the bottom. The panel swings down for easy access to the wiring locations.

Removable connectors and signal input boards

The T56 uses removable signal input boards and communication boards for ease of wiring and installation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring. The T56 has three slots for placement of up to two signal input boards and one communication board

Slot 1-Left

Profi board

Slot 2 – Center

Signal Board 1

Slot 3 – Right

Signal Board 2

3.1.2.

Signal input boards

Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed enclosure.

NOTE:

For the purpose of replacing factory-installed signal input boards, Rosemount Analytical Inc. is the sole supplier.

3.1.3.

Digital communication boards

HART digital communications is standard on the T56. A Profibus DP communication board is available as an option for the T56 communication with a host. HART communications supports

Bell 202 digital communications over an analog 4-20mA current output. Profibus DP is an open communications protocol which operates over a dedicated digital line to the host.

3.1.4

Alarm relays

Four alarm relays are supplied with the switching power supply (85 to 264VAC, -03 order code) and the 24VDC power supply (20-30VDC, -02 order code). All relays can be used for process measurement(s) or temperature. Any relay can be configured as a fault alarm instead of a process alarm. Each relay can be configured independently and each can be programmed as an interval timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or low activation or USP*) and deadband are user-programmable. Customer-defined failsafe operation is supported as a programmable menu function to allow all relays to be energized or not-energized as a default condition upon powering the analyzer. The USP* alarm can be programmed to activate when the conductivity is within a user-selectable percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is installed.

Sensor wiring to signal boards

Plug the pre-terminated sensor cable connector directly into the turbidity signal board mating connector.

WARNING


Electrical installation must be in accordance with the National Electrical Code

(ANSI/NFPA-70) and/or any other applicable national or local codes.

Sensor

The sensor cable is pre-wired to a plug that inserts into a receiving socket on the signal board.

See Figures 3-1. The cable also passes through a strain relief fitting. To install the cable:

1. Remove the wrenching nut from the strain relief fitting.

2. Insert the plug through the hole in the bottom of the enclosure nearest the sensor socket.

Seat the fitting in the hole.

3. Slide the wrenching nut over the cable plug and screw it onto the fitting.

4. Loosen the cable nut so the cable slides easily.

5. Insert the plug into the appropriate receptacle. To remove the plug, squeeze the release clip and pull straight out.

6. Adjust the cable slack in the enclosure and tighten the cable nut. Be sure to allow sufficient slack to avoid placing stress on the cable and connections.

7. Plug the cable into the back of the sensor. The sensor is rated to IP65 when properly connected to the cable. To prevent possible water damage to the connector contacts, be sure the cable receptacle and the connector on the back of the sensor are dry when connecting or disconnecting the cable.

8. Place the sensor in either the measuring chamber or the calibration cup. The sensor must be in a dark place when power is first applied to the analyzer.

NOTE:

If “S1 Warning” appears, check sensor cable connection and confirm sample water flow at debubbler drain outlet.

Section 7.0 Calibration

7.1 Calibration – Introduction

Calibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated laboratory instrument, or standardizing to some known reference. Completion of Quick Start upon first power up enables live measurements but does not ensure accurate readings in the lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings.

7.2

Turbidity

This section describes how to calibrate the turbidity sensor against a user-prepared standard as a 2-point calibration with deionized water, against a 20 NTU user-prepared standard as a single point calibration, and against a grab sample using a reference turbidimeter.

To calibrate the turbidity sensor, access the Calibration screen by pressing ENTER/MENU from the main screen, select S1 or S2 Measurement and press ENTER/MENU. Press INFO at any time to learn more about this procedure. A yellow screen will appear with detailed instructions and information.

The following calibration routine is covered:

1. Slope Calibration Slope cal with pure water and a standard of known turbidity

2. Standardize Calibration

Standardizing the sensor to a known turbidity

3. Grab Calibration Standardizing the sensor to a known turbidity based on a reference turbidimeter

1. To calibrate the turbidity loop using Slope Calibration with pure water and a standard of known turbidity, follow the step-by-step procedures displayed on-screen.

2. To calibrate the turbidity loop using Standardize Calibration by Standardizing the sensor to a known turbidity, follow the step-by-step procedures displayed on-screen.

Slope Calibration – Turbidity

This section describes how to conduct a 2-point calibration of the turbidity sensor against a user-prepared 20NTU standard. The calibration requires two steps. First, immerse the sensor in filtered water having very low turbidity and measure the sensor output. Next, increase the turbidity of the filtered water by a known amount, typically 20 NTU, and measure the sensor output again. The analyzer takes the two measurements, applies a linearization correction (if necessary), and calculates the sensitivity. Sensitivity is the sensor output (in mV) divided by turbidity. A typical new sensor has a sensitivity of about 10 mV/NTU. As the sensor ages, the sensitivity decreases. The figure below illustrates how turbidity calibration works. Before beginning the calibration, the analyzer does a dark current measurement. Dark current is the signal generated by the detector when no light is falling on it. The analyzer subtracts the dark current from the raw scattered light signal and converts the result to turbidity. In highly filtered samples, which scatter little light, the dark current can be a substantial amount of the signal generated by the detector.

Standardize Calibration – Turbidity

The turbidity sensor can also be calibrated against a commercial standard. Stable 20.0 NTU standards are available from a number of sources. Calibration using a commercial standard is simple. Filtered deionized water is not required. Before beginning the calibration, the analyzer does a dark current measurement. Dark current is the signal generated by the detector even when no light is falling on it. The analyzer subtracts the dark current from the raw scattered light signal and converts the result to turbidity. In highly filtered samples, which scatter little light, the dark current can be a substantial amount of the signal generated by the sensor.

Grab Calibration – Turbidity

If desired, the turbidity sensor can be calibrated against the turbidity reading from another instrument. The analyzer treats the value entered by the user as though it were the true turbidity of the sample. Therefore, grab sample calibration changes the sensitivity, it does not apply an offset to the reading.

Maintenance

Sensor

Cleaning the sensor

Clean the sensor by rinsing it with water followed by wiping with a soft tissue. If water is inadequate, wash with a mild detergent solution followed by thorough rinsing with water. Do not scratch the lamp or photodiode windows.

If mineral scale is present, use a dilute acid solution applied with a cotton swab to clean away the deposit. Rinse thoroughly with water.

Do not use abrasive cleaners or solvents.

Replacing the lamp/LED board

The USEPA-compliant sensor uses a tungsten filament lamp (PN 1-0901-0004-EPA) as the light source. The lamp has an expected life of about one year. The ISO-compliant version uses an infrared LED (PN 1-0901-0005-ISO). Its expected life is three years. The 56 analyzer continuously monitors the source intensity and corrects for changes in source intensity caused by age.

When the source intensity becomes too low, the analyzer warns the user. The user should replace the lamp as soon as possible.

To replace the lamp/LED board:

1. Turn off power to the analyzer.

WARNING

Explosion Hazard. Do not disconnect equipment when a flammable or combustible atmosphere is present.

2. Remove the sensor from the measuring chamber and disconnect the cable.

WARNING

Before removing the sensor, be absolutely certain that the process pressure is reduced to 0 psig and the process temperature is lowered to a safe level!

Appendix

This procedure describes how to verify linearity between turbidity and TSS.

1. Collect a sample of the process liquid-you may need 10 L or more if you use the Clarity II for measuring turbidity. If you use a laboratory turbidimeter, you will need less volume. The Clarity II requires about 500 mL for the measurement; laboratory turbidimeters require 50 mL or less. Verify that the turbidity of the sample is less than 200 NTU.

Store in a clean bottle.

2. Filter a portion of the sample to obtain at least 5 L of dilution liquid. The filtrate is needed to dilute the sample in subsequent steps. Verify that the turbidity of the dilution water is low. If filtering the sample is impractical, use deionized water for dilution.

3. Measure the total suspended solids (TSS) in the sample obtained in step 1. Thoroughly mix the sample before withdrawing liquid. A magnetic stirrer is best, but inverting the sample repeatedly for about a minute works, too.

Avoid violent shaking or mixing. Refer to any standard reference work on water and wastewater testing for the procedure for determining TSS.

4. Dilute the sample from step 1, by a factor of 0.9, 0.7, 0.5, 0.3, and 0.1. See the table for recommended volumes.

Measure TSS and turbidity for each dilution. For lower TSS values, use a larger volume of sample.
