■ Summary
LZB-FL series rotary shunt flow meter is a kind of instrument composed by throttling device(orifice plate) of main pipeline and rotary flow meter(glass tube flowmeter,metal tube flowmeter) of separate pipeline,which can get the main pipeline flow through measuring the separate pipeline flowrate.
■ Features
◆Use the stable small-bore flow meter to measure the large flowrate;
◆Easy read,convenient use and maintenance,compact structure design;
◆When clean or change graduated tube,it is unnecessary to stop the main pipeline flow(equip with stop valve);
◆This series flow meter adopt to the principle of differential pressure and orifice plate machinery principle,can be widely used;
◆Rangeability:5:1
◆Composed with metal tube flowmeter can equip with 4~20mA current signal output.
