flow rate transmitter variable area

The Flow Rate Transmitter is ideal for batching, industrial process control, mobile hydraulic equipment and computer / PLC controlled hydraulic system monitoring applications. It is designed without delicate internal components to break, abrade, or corrode. The weather tight construction includes a rugged cast aluminum enclosure built to NEMA 4X standard for installation outdoors. This variable area flow meter is used to measure air, gas, oil, and water. The transmitter provides a visual indication of flow rate that matches the transmitted output for direct reading.

Description
  • Simple to Install: All transmitters are factory calibrated and ship fully assembled. Simply install the transmitter into your system and apply power. No straight plumbing required at inlet or outlet.
  • Industry Standard Outputs: Transmitters provide proportional analog or pulse outputs that will drive popular data acquisition devices, meters and analog input cards.
  • Direct Reading: All transmitters provide a visual indication of flow rate that matches the transmitted output.
  • Weather-Tight Construction: The rugged cast aluminum enclosure is built to NEMA 4X standard and allows installation outdoors and in environments where liquid tight seals are required.
  • Rugged and Reliable: Without delicate internal components to break, abrade or corrode, the flow transmitter will provide many years of low-maintenance service

Electronics
Electronic Transmitter Performance:
Power Requirements:

12-24 VDC

Load Driving Capacity:

4-20mA: Load resistance is dependent on power supply voltage. Use the following equation to calculate maximum load resistance: Max Loop Load (Ω) = 50 (Power supply volts – 12).

0-5 VDC: Minimum load resistance 1000.

1-5 VDC: Minimum load resistance 25 K Ω

Square Wave Pulse: Minimum load resistance 1000 Ω

Transmission Distance:

4-20mA and 1-5 VDC (regulated) are limited only by wire resistance and power supply voltage.

<200 feet recommended for 0-5 VD (regulated) C and square wave pulse.

Over-Current Protection:

Self limiting at 35mA

Resolution:

10-bit (0.1%)
