1) Measurement characteristics
The measurement performance is better for portable and handheld flow meter. This is because their power are battery operated,and fixed meter is adopted by AC or DC power supply, even if the DC power supply, generally from AC conversion. AC power supply has a certain impact on the measurement performance, in the case of weak sensor signal, the measurement effect is better for them.
2) Comparison of power supply
hand-held and portable type meters are more convenient to use. Fixed meter requires external 24VDC or 220VAC AC power, portable and handheld meters are internal battery power, portable meter for 50 hours, handheld meter for 14 hours.
3) Heat measurement
fixed and portable meter can be equipped with a pair of Pt1000 to achieve heat measurement, it is no this function for handheld meter.
4) Output options
Wall mounted flow meter have many output options like 4-20mA,OCT,Relay,RS485,Datalogger,HART,NB-IOT or GPRS;
Portable flow meter’s output is optional for 4-20mA,OCT,Relay,RS485,datalogger,etc.
Hand-held flow meter ‘s output is optional for OCT, RS232 and data storage options.
