Flow Rate Monitoring
Quick Specs...
- Accurate Flow Rate Indication with Integral Visual Confirmation
- 0-10 VDC Analog Signal @ 1 mA Max
|
|
|
Overview / Design Principle:
Gems Sensors popularized the RotorFlow’s paddlewheel design by combining high visibility rotors with solid-state electronics that are packaged into compact, panel mounting housings. They provide accurate flow rate output with integral visual confirmation...all with an unprecedented price/performance ratio.
Applications:
- Water Purification/Dispensing Systems
- Chemical Metering Equipment
- Lasers and Welders
- Water Injection Systems
- Semiconductor Processing Equipment
- Chillers and Heat Exchangers
