High Precision RS485 RS232 Gas Pressure Test Gauge Gas Mass Flow
Meter
Product Introduction of Mass Flow Meters
Gas mass flowmeter main function is to measure a variety of single
gas or mixed gas, no control function, divided into digital type
with display (left), analog type without display (right), digital
type mainly has RS485 communication can be connected to a computer
or PLC can be field panel adjustment: analog type output 0-5V or
4-20MA can not be field adjustment, can be connected to PLC or flow
control instrument.
FEATURES of High quality flow meters
1. Small size, does not occupy space
2. With display, fast reading flow rate
3. Good material, longer service life
4. Control mode and analog quantity can be selected
5. High accuracy
6. Fast response time
7. Low failure rate

SS316L MATERIAL
The base material of the flow meter controller is S316L,and the
material that contacts the gas is also SS316L.It can measure some
weak corrosive gases. When measuring other sfrong corrosive gases
and organic solvent gases, it should be declared when ordering.
| 0.5%HIGHPRECISION
The standard accuracy of gas mass flowmeters is 0.5%. 1.0% of
reading,and the repeatability of 0.5% full scale accuracy is
0.2%.The accuracy of the
controller is 1.0%(full scale accuracy) | FLOW CONTROLLER
The flow range of the miniature gas massflowcontroller is the same
as that of the flowmeterthe valve control range ratio is 50:1and
the
proportional control valve accuracy is 1.0%.
