Differential pressure flow meter
Product Overview
Smart multi parameter flow meter combines differential pressure transmitters, temperature acquisition, pressure acquisition, and flow accumulation to display work pressure, temperature, instantaneous, and cumulative flow in place. The gas and steam can be automatically compensated for temperature and pressure to realize the function of displaying standard flow and mass flow at the site. And can use dry battery work, can be directly used with the differential pressure flow meter.
Main features
1.Liquid crystal lattice Chinese characters display, intuitive and convenient, simple and reset operation;
2.Equipped with non-contact magnetic data settings, without opening the cover, safe and convenient;
3.Can be connected with a variety of differential pressure flow sensors (such as orifice plate, V-cone, Annubar, elbow and other differential pressure sensors);
4.With temperature / pressure sensor interface, strong interchangeability. Can be connected to Pt100 or Pt1000, pressure can be connected to gauge pressure or absolute pressure sensor, and can be modified in sections; (optional);
5.Measuring a wide range of media, can measure steam, liquid, gas, etc.;
