ОВАЛ РАСХОДА

Smith 2014-oval gear flow meter is a volume measuring instruments, measured mainly by Shell, the oval gear transmission and rotor components. It is using in the pipeline for continuous or intermittent liquid flow measurement and control instrumentation. It has wide range, excellent accuracy, small pressure loss, viscosity strong adaptability and high viscosity liquids capable of measuring temperature calibration convenient, simple to install, and other advantages. Apply to crude oil, chemicals, chemical fiber, traffic, commerce, food, medicine and health care, scientific research and military industries in the flow measurement. SMITH2014 oval gear flow meter can be directing the cumulative flow, instantaneous flow, a single flow, and so on, can also be output pulse signal, 4-20mA, or 1-5 V analog signals 4-20mA +HART, MODBUS, communications and other support 232,485. Smith and mechanical or electronic controller grant awarded controller combinations can be realized for different types of filling, control, and other functions approved. Features Flow meter all parts are surface from the precision machining, casting without surface defects, smooth surface appearance. Flow meter designed using patented technology, not demolished and professionals can be installed at the scene, and re-installed, not to change the original measurement accuracy. Flow meter used waterproof design. Transmission Chain short, the work is urgent and reliable high precision and stability. Products small size, light weight, and is particularly applicable to factories, wharves, ships, removal and demolition of the more troublesome areas. Flow meter site can show that the cumulative flow, instantaneous flow,a single flow.
