Description
Features and Benefits
- Displays instantaneous flow rate, total and accumulated total
- Large LCD 17mm (0.67”) and 8mm (0.31”) for flow rate and total
- Measures 6:1 range with ± 3% F.S. accuracy
- Scaled pulse output according to accumulated total
- Liquid flow ranges from 4 GPH (15 l/h) in 1/2” flow meter to 3000 GPM (12000 l/m) in 8” flow meter.
- Gas flow ranges from 40 SCFH (1 Nm³/h) in 1/2" flow meter to 20,000 SCFM (600Nm³/m) in 8” flow meter.
Applications
- Power and Gas (Utility Industry)
- Process Control for Liquids and Gases
- O2 (Oxygen) Service Applications
- Biodiesel Blending Process
Principle of Operation
The wet/wet pressure sensor detects the differential pressure created through the calculated flow nozzle. A scaled pulse output according to the accumulated total. Requires a 24Vdc supply not included (option PS-24).
