F56 metal Tube Float Flow meter Series are used for measureinstantaneous and accumulated flow rate of liquid, gas and steam inclosed pipelines. It is suitable for metering flow value on site orelectronic remote. The measuring principle is based on thehydrodynamic effects,This makes float moving from bottom to top invertical Pipe. As the displacement of float is in related to flowrate, which can be read from the indicator by means of the magneticdrive system in non-contact form . Also, flowmeters outputelectrical signal (4-20)mA / hart communication protocol with high/ low limit Warning switches/integrating flow PCB broad can beconfigured.
