Product features
Sepecial designed for low pressure gas flow measurement in pipes of 3mm and 8mm.，Conduct statistical recording of fluid data
Support multiple connection modes, easy to install and use.
The output mode is flexible, which can either automatically upload data through communication interface .
Excellent performance on the anaesthesia machine spreadsheet or output data from the upper computer, or a linear analog voltage can be output through the analog interface.
LED displays instantaneous flow rate and cumulative flow rate, allowing field button configuration of flow meter parameters.
It can record the maximum and minimum values of instantaneous flow since power on, and it has the function of over range
All measuring ranges are high stability,accuracy and excellent repeatability.

Remark:1.The plug of the wiring SN5-50 is CDH-5;
2.The above parameters at 20 ° C, 101.325 kPa measured.
Product selection
*The unit of maximum flow is SLPM,for example 5 represents maximum flow of 5SLPM;
For co2 and laughing gas, the maximum flow of MF4003 is 2，3，4instead of 5,and the maximum flow of MF4008 is10,20,30,40 instead of 50.
**The sensor's standard output is analog voltage, and RS232 and RS485 are options.
