Setting-Up

Supplying Power

The flowmeter can be powered in one of two ways: through the power jack

using the supplied AC adapter or through the mini-DIN connector. The DC

power input connector is shown below along with the power requirements.

Power Supply: 7.5 VDC ±1.5 V, 300 mA maximum

When supplying power through the TSI-supplied interface cable, line up the

arrow on the connector with the bottom side of the flowmeter. Flowmeter

connector pin-out designations are shown below.

Connecting Filter and Flow Tubes

The Models 4040/4043/4045 have an exposed thermal flow sensor, which

must be protected from foreign matter and particles in the gas flow. TSI has

supplied a filter, which should be connected to the inlet of the flowmeter,

however, any filter will work as long as it has a minimum efficiency of

99.9%.

Caution

Always use a filter on inlet of flowmeter. Failure to

filter the gas flow may change the calibration and/or

permanently damage the sensor.

Note: Flow direction is identified by the large arrow printed on the

bottom side of the flowmeter.

After attaching the filter, connect the flow tube, to the inlet, of the filter.

Connecting a tube to the outlet of the flowmeter will create back pressure.

See Appendix A for flowmeter accuracy specifications when operating at

various pressures. In general, minimize back pressure on the flowmeter to

maintain higher accuracy.

RS232 Configuration and Operation

Many flowmeter operating parameters can be easily configured through the

RS232 serial port. Likewise, the flowrate, temperature, pressure, and

volume can be read through the serial port. Refer to the Series 4000/4100

RS232 Serial Command Set manual for a detailed description of the

commands and command syntax.
