Smith speed type gas flow meter speed type based on the principle of electromechanical integration design; Due to the special technology processing, its characteristic is simple and compact structure ,it has high precision and reliability; Temperature and pressure compensation type flowmeter, the precision is more accurately, it  can  measured the condition flow or standard condition flow; when importing and exporting ,it need to install straight pipe, It need large installation space; The surrounding environment should not have strong electromagnetic field and violent vibration;

The main technical indexes:

1, flow: 3 ~ 20000 m3 / h
2, diameter: DN15-DN300mm
3, pressure level: 1.6 MPa, 2.0 MPa, 4.0 MPa, 6.3 MPa, 10.0 MPa
4, working temperature:-40 ℃ ~ + 450 ℃
5, precision: plus or minus 0.75%; Plus or minus 1.00%; Plus or minus 1.50%
6, range than: as superior
Display form: the show accumulative total flow, transient flow, single flow (back to zero count) electronic LCD counter, etc
Output form: single pulse; Many (n) road pulse; 4 ~ 20 mA;4 ~ 20 mA + HART output; 1 ~ 5 V output; RS232 communication; RS485 communication; MODBUS agreement
