Designed in three-wire or two-wire system, E Series Display Circuit is a newly emerged compact circuit of Vortex Flow Meter. Its amplified circuit belongs to the Analog type. Within the conventional flow range, the flow rate of gas, liquid and steam can be measured in high accuracy through using this E Series Display Circuit. In addition, switches can be set up to adapt to a variety of medium-calibers and various kinds of measurements. Remote data processing and remote signal circuit are divided into three-wire system and two- wire system. The three-wire system can be connected with RS485 communication equipment; it is also battery-powered. Using 4-20mA current output, the two-wire system can provide isolated original pulse output.

Applicable Caliber: DN15-DN300, other caliber agreement supply.
Applicable medium: gas, steam and liquid.
