Flange type 4-20ma output digital rotameter flowmeter for Gas
Gas rotameter for measuring with a rota. It first converts the flow rate to the turbine speed, and then converts the speed into an electrical signal proportional to the flow rate. This flow meter is used to detect instantaneous flow and total accumulated flow, the output signal is frequency, easy to digitiz
digital rotameter
