AVF250S Series
The AVF250S series is a Micro float flowmeter developed by ALIA, with a simple structure and easy installation, which is very suitable for the measurement of small flowrate of gas or liquid. The design of the trimming needle valve makes it convenient to adjust the flowrate. Combined with the flow regulator, the flow purge device is formed to achieve constant flowrate output. The AVF250S is widely used in petrochemical, oil refining, fertilizer, steel, medicine and other industries.
Features
- Measuring liquids or gases
- Local measurement, setting and monitoring of very low flow rates
- LCD display with 4-20 mA output and HART communication
- 1/4″ NPTF, 1/2″ NPTF, Compression Fittings or Flange connection
- Needle valve for flow regulation
- High resistance to pressure and temperature
- Flow regulators are used to provide constant flow rates in the case of variable inlet or outlet pressures
