Page 7: Operation
OPERATION FlowStream flowmeters accurately measure the mass flow rate of most gases. The flow rate is determined by measuring the pressure drop across a unique internal restriction, known as Laminar Flow Element (LFE). The restriction is designed such that the gas molecules are forced into moving in parallel paths along the entire length of the passage for the entire range of operation of the device. -
Page 8: Using Flowstream With Different Gases
The internal temperature sensor is located above the inlet port, very close to where the gas enters the meter. This ensures accurate measurement of the gas temperature. However, because the temperature sensor is embedded inside the flowmeter body, if ambient temperature is different from gas temperature, there would be a discrepancy between what the sensor reads and the true gas temperature. -
Page 9: Wiring Diagram
WIRING DIAGRAM Wiring for 4-20mA Transmitters Figure 2 shows a typical 2-wire, 4-20mA transmitter wiring for use with FlowStream flowmeters. Maximum loop resistance is related to the available supply voltage. Since the flowmeter requires 10 volts to operate, the voltage drop across the loop resistance at full-scale flow output (20mA) must be added in to determine the minimum supply voltage. -

Figure 3. Required Supply Voltage vs. Loop Resistance Hazardous Environment Wiring Intrinsically Safe wiring must be installed in accordance with Article 504 of NEC, ANSI NPF 70 and Control Drawing Number 7577, Revision 00 (Figure 4, below). The transmitter approval by the Canadian Standards Association for installation in Hazardous environments is based on installation through an Intrinsic Safety Barrier. -
