AW-Lake Flow Rate Transmitter


AW-Lake 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.

AW-Lake Flow Rate Transmitter Applications:

  • 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
