<1>Outline
Smith2015 type Roots flow meter is short for Roots flowmeter . It is used in the pipeline for continuous or intermittent liquid flow measurement and control.. It has higher accuracy、 reliability、light weight、long service life、low operation noise and installation convenience and many features . The series of Smith2015 LuoCi Roots Flow meter can display the cumulative flow、instantaneous flow、a single flow and so on. It can also 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. Combinated with Smith mechanical or electronic batch controller,it can realize for different types of filling, control, and other functions approved.
Implementation standards of the Flow meter: NIST (professional standards of USA technical standards Office)JB / T 9242-1999《volumetric flow meter GM technical conditions》.QB/SML01-2001 "LuoCi Roots flow meter"
