Product features
Multi-sensor integration is implemented on a single chip, which greatly improves the range ratio of the flowmeter.
The zero point stability of the sensor is greatly improved compared with the traditional thermal mass flowmeter.
The simplified structure brought by technological progress makes the flow meter greatly reduce the pressure loss compared with the traditional mechanical instrument, and greatly reduces the energy consumption.
Use LCD to display instantaneous and cumulative flow, clear and intuitive, easy to read.
This flowmeter is equipped with RS485 communication module, which can realize centralized management with the upper computer network.
4~20mA standard current signal output and pulse output can be selected.
Approved by the national explosion-proof certification, marked as Exia IIC T4, can be used in flammable and explosive gases.

Product selection
In addition to the models listed in the model selection table, the company can also customize the products required by users according to special requirements (such as other diameters、flow range).If need, please contact the manufacturer directly.Production license of this series of products:Chuan produce no.0000036:Explosion permit:GYB15.1917X.
Remark:1.The default unit of maximum flow and minimum flow is Nm³/h,under the standard state (20 ℃) 101.325 kPa.
When selecting the default unit, write only Numbers;When selecting other units, the units must be written after the maximum flow;
For example...-4-400kg/h- represents the minimum flow rate and the maximum flow rate are 4 and 400kg/h respectively;
The minimum flow can be selected as the value in the above table or larger than the value listed in the above table, for example, MF50 minimum flow can be selected 4 or 10;
The maximum traffic can be selected from the values in the table above or smaller than those listed in the table above, for example MF50 maximum traffic can be selected 400 or 300
2.The internal battery power supply type only has field display without any output signal.
