ROOTS FLOW METER

Roots flow meter short called lumbar round flow meter .It is mainly using in the liquid flow in pipes and continuous or intermittent measurement Meter. It has higher accuracy, reliability, light weight, long service life, low operation noise and installation convenience and many features . The series of Smith2015 lumbar Flow meter can be directing the cumulative flow, instantaneous flow, a single flow and so on. It can also be output pulse Signal 4-20mA, or 1-5 V analog signals,communications RS232,RS485 4-20mA +HART,MODBUS agreement. It is widely used in petroleum, chemicals, electric power, metallurgy, transport, food processing, medicine, national defense, business and trade sectors such as oil and oil products, chemical solutions, such as fluid precision measurement. Smith and mechanical or electronic controller grant awarded controller combinations can be realized for different types of filling, granted control functions. Flow meter implementation of the standards: NIST (USA technical standards for professional standards),JB / T 9242-1999 (volumetric flow meter GM technical conditions).
