There are seven keys for menu navigation. The MENU key is used to toggle between the menu

and the measure screen. Pressing the Menu key provides options for calibration, configuration,

communications, outputs and relays. Refer to the AV38 Manual for Details.

3. INSTALLATION

The AquaTrace measurement system is mounted on a 12 inch X 12 inch panel with four ¼" mounting

holes. Use ¼ inch bolts with washers to mount the panel to a wall.

The sample supply is connected to the fitting at the bottom of the flow chamber. The sample supply

should be regulated to control pressure and flow. The sample pressure should not exceed 60 psi. The

sample flow rate should be regulated between 50 mL/min and 400 mL/min. The sensor will operate

properly across this range, however rapid variations in flow can cause temporary measurement

fluctuations. To insure a stable measurement, the sample supply should be regulated to provide a

consistent flow rate to the sample chamber.

The outlet fitting on the sample chamber must be connected to a vented drain. Excessive tubing length

or pipe restrictions that result in back pressure to the outlet are not allowed.

The inlet and outlet port on the sample chamber are supplied with compression fittings for use with ¼

inch OD tubing. When the inlet and outlet are to be directly plumbed, remove the compression fittings

and connect to the flow chamber with 1/8 inch NPT fittings

Note that the tubing and plumbing used to install the AquaTrace system must not be gas measuring the

process. Verify that all plumbing permeable. Stainless steel, Kynar PVDF and polypropylene are

relatively impermeable to oxygen. Other materials such as silicone are gas permeable and allow oxygen

contamination that will prevent the system from accurately components are suitable for use with a low

oxygen process.

Thermo Scientific AquaSensors

DataStick sensors connected to the AV38 communicate via MODBUS

RTU. As such, the AV38 can be used to select any two of the DataStick

sensors on the bus for display, current output reporting and relay alarms by

selecting the desired station addresses. When there is no DataStick

sensor connected at the selected network address, the measure screen

will indicate "DataStick Absent".
