Energoflow EFS-R Reference Rotary Gas Meters

Energoflow EFS-R Reference Rotary Gas Meters is intended for installation on reference calibration rigs for calibration and verification of gas meters of any type with air as the operating environment.
Energoflow EFS-R Reference Rotary Gas Meters

The meters are equipped with an electronics unit (EU) and rotary transducer with mounted binary pulse-frequency sensors and pressure sensors. The meter EFS-R is intended for measuring the volume of gas passing through its input channel of the circular section. The gas flow volume is transmitted to a PC via the EU.

The meters are designed for vertical installation on the reference equipment with DN 20mm, DN 25mm, standard size G 2,5, G 10, G 16. The connection between the meter and PC is carried out via RS-485. Exchange protocol - Modbus RTU. “Start-stop” synchronization is of two-wire type based on the communication line RS-485.
