MODEL CLARITY II SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

SECTION 1.0.

DESCRIPTION AND SPECIFICATIONS

• 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

• RANGE 0-200 NTU

• RESOLUTION 0.001 NTU

• FULL FEATURED ANALYZER with fully scalable analog outputs and optional fully
programmable alarms

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

Clarity II is a trademark of Emerson Process Management.

FEATURES AND APPLICATIONS

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 tur-

bidity of filtered drinking water. Because it measures
turbidity as high as 200 NTU, Clarity II is also suitable
for most raw waters. 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 Solu Comp II analyzer. Menu flows
and prompts are so intuitive that a manual is practical­ly not needed. Analog outputs are fully scalable. An
optional alarm board with three relays is also avail­able. 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.

A dry check is also available to periodically confirm
Clarity II operation.

2.2 INSTALLATION — ANALYZER

2.2.1 General Information

1. Although the analyzer is suitable for outdoor use, do not install it in direct sunlight or in areas of extreme tem­peratures.

2. Install the analyzer in an area where vibrations and electromagnetic and radio frequency interference are min­imized or absent.

3. Keep the analyzer and sensor wiring at least one foot from high voltage conductors. Be sure there is easy
access to the analyzer.

4. Do not run AC power and relay wiring through the top conduit openings. Keep AC power and relay
wiring separate from other wiring in the analyzer after installation.

5. The analyzer is suitable for panel, pipe, or surface mounting. Refer to the table below.

6. See Section 3.1 for removal of conduit knockouts.

7. To reduce the likelihood of stress on wiring connections, remove the hinged front panel (-11 models) from the
base during wiring installation. Allow sufficient wire length to avoid stress on conductors.

2.3 INSTALLATION — DEBUBBLER ASSEMBLY

See Figure 2-4 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.

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.

2.4 INSTALLATION — SENSOR

Unscrew the nut on the side of the debubbler. Insert the sensor in the mouth of the measuring chamber. Be sure
the pin on the debubbler lines up with the hole in the sensor. Replace the nut. Remove the protective cap from
the sensor and screw the cable onto the receptacle. The plug and receptacle are keyed for proper alignment.

2.5 SAMPLE POINT

Locate the sample tap to minimize pickup of sediment or air. See Figure 2-6. If possible, install a sampling port
that extends one or two inches (25 - 50 mm) into the pipe. Use ¼ inch OD rigid plastic tubing. Avoid soft plastic
tubing if possible. To reduce sample lag time, install the debubbler and flow chamber as close to the sample tap
as possible.

WIRING

3.1 PREPARING CONDUIT OPENINGS

The analyzer enclosure has five conduit openings. Two are
open and three are knockouts.

Conduit openings accept 1/2-inch conduit fittings or PG 13.5
cable glands. To keep the case watertight, block unused
openings with NEMA 4X or IP65 conduit plugs.

NOTE

Use watertight fittings and hubs that comply with the
requirements of UL514B. Connect the conduit hub to the
conduit before attaching the fitting to the analyzer
(UL508-26.16).

Figure 3-1 shows how to remove the knockouts. The knock­out grooves are on the outside of the case. Place the screw­driver blade on the inside of the case and align it approxi­mately along the groove. Rap the screwdriver sharply with a
hammer until the groove cracks. Move the screwdriver to an uncracked portion of the groove and continue the
process until the knockout falls out. Use a small knife blade to remove the flash from the inside of the hole.

3.2 POWER, ALARM, OUTPUT, AND SENSOR CONNECTIONS

3.2.1 General Information

The analyzer is available in two mounting configurations.The positions of the power, alarm, output, and sensor ter­minal blocks are different in each. See Figure 3-2 (panel mount) or Figure 3-3 (pipe/wall mount).

To reduce the likelihood of stress on wiring connections, keep the hinged front panel (-11 option only) attached to
the back cover while installing wiring. Be sure there is sufficient cable within the analyzer enclosure to avoid stress
on conductors and connections.

For ease of wiring, connections for power, outputs, and alarms are removable.

3.2.2 Sensor

The sensor cable is pre-wired to a plug that inserts into a receiving socket in the analyzer. See Figures 3-2 and
3-3 for the locations of the sockets. If you are using a single input analyzer, be sure to plug the sensor into the
SENSOR 1 receptacle. 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.

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 appled to the analyzer.

3.2.3 Power, Alarm, and Ouput

AC wiring should be 14 gauge or greater. Provide a switch or breaker to disconnect the analyzer from the main
power supply. Install the switch or breaker near the analyzer and label it as the disconnecting device for the
analyzer.

Keep sensor and output signal wiring separate from power wiring. Do not run sensor and power wiring in the same
conduit or close together in a cable tray.

For best EMI/RFI protection use shielded output signal cable enclosed in an earth-grounded metal conduit.
Connect the shield to earth ground.

Do not apply power to the analyzer until all connections are secured and verified.

3.2.4

The sensor cable is rated as Non-Incendive field wiring by FM and CSA.

The AC power wiring, analog output wiring, and alarm wiring (optional configuration) is not

rated as Non-Incendive
and must be installed in metal conduit. Refer to the FM and CSA control drawings herein, Figures 3-4 through 3-7, for
proper installation in hazardous areas.

WARNING: RISK OF ELECTRICAL SHOCK

AC connections and grounding must be in compliance with UL
508 or local electrical code. DO NOT apply power to the analyz­er until all electrical connections are verified and secure.
