Other prerequisites for appropriate use include:

Observing the instructions, notes and requirements set out in this

•

instruction manual.

Observing all local safety regulations.

•

Observing all warnings and cautions in the documentation regarding

•

all products used in this measurement system, including the sensor, mounting hardware, AV38 electronics and cabling.

Observing the prescribed environmental and operational conditions.

Correct Disposal of Unit

•

When the Turbidity System is taken out of service, observe the local environmental regulations for correct disposal.

2. PRODUCT DESCRIPTION

2.1 Drinking Water Turbidity

The LaMotte 2020 ClearTrace Inline Turbidity System continuously monitors low-range turbidity and temperature in drinking water applications.

In the standard system configuration, data is reported through a local display and a scalable4–20milliamp current output. All functions can be accessed through a digital network with or without the local display interface.

The Turbidity System uses a pre-calibrated turbidity probe mounted in a DataStick and attached to a sample chamber specifically designed to prepare water for low-range turbidity measurements. The chamber removes bubbles from the water sample so that solid particles can be accurately detected. Because the chamber volume is only 135 milliliters, only a small amount of a turbidity standard is necessary to perform EPA mandated calibrations.

A white light source in the chamber lid illuminates suspended particles with a collimated white light. The chamber lamp will provide collimated white light for up to two years and is easily changed from the top of the system.

Measurement data from the turbidity probe is communicated through the DataStick communication adapter for direct computer communications.

2.2 Calibration Kits

Calibration kits containing calibration standards and accessories are available for use with the 2020 ClearTrace.

3. MOUNTING, WIRING AND PLUMBING

Figure 3.1: Wall mounting Clearances

3.1 Mounting

The 2020 ClearTrace Turbidity System is mounted on a 12 inch x 12 inch panel with four ¼ inch mounting holes. Use ¼ inch bolts with washers to mount the panel to a wall. Make sure the sample chamber is level and plumb to insure proper water levels are maintained in the sample chamber. It is important to note that the system must be fixed securely to the wall to insure the chamber does not move when handled or touched.

Mounting tools and equipment:

•

½ inch Drill with drill bit for appropriate wall anchor.

•

Four ¼ diameter bolts – 1.5 inches long.

•

Four ¼ inch ID flat washers

•

Wrench to turn bolts

•

Level to insure the system is level when mounted

General Mounting Instructions:

1. Place the 12x12 inch panel on the wall where it is to be mounted and mark the placement of the upper left hole.

2. Drill a mounting hole for the upper left corner with a masonry drill bit.

3. Mount the Turbidity System with the upper left bolt.

4. Using a level, rotate the system until level, then mark the other three

mounting holes.

5. Rotate the Turbidity System out of the way and drill the other three

mounting holes.

6. Place all four bolts with washers and tighten. Use shims if necessary to insure the sample chamber is level.

3.2 Plumbing

The Turbidity System has an INLET, an OUTLET and a DRAIN. Barb fittings are provided for the INLET and OUTLET in the event that

3/8 inch ID tubing is used. When piping is used instead of tubing, remove the barb fittings to install ¼

inch NPT threaded pipe for the INLET, OUTLET and DRAIN. OUTLET and DRAIN Plumbing Recommendations: Use straight ¼ inch

NPT threaded pipe that extends to a vented drain. Pipe restrictions that result in back pressure for OUTLET and DRAIN are not allowed.

INLET Plumbing Recommendations: Use 3/8 ID tube or ¼ inch NPT threaded pipe from sample source.

Flow rate must be between 250 to 750 ml/min (4 to 12 gph). If the source is under pressure, use an appropriate flow or pressure valve to obtain consistent flow. The turbidity sample chamber has an overflow weir that must not be restricted.
