Multi-Parameter Differential Pressure Transmitter
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.;
6.With excellent nonlinear correction function, greatly improve the instrument's linearity;
7.The ratio of 1:100 (special requirements can be 1:200);
8.With full-featured HART protocol, remote parameter setting and debugging; (optional);
9.The converter can output frequency pulse, 4 ~ 20mA analog signal, and has RS485 interface, can be directly connected with the computer, the transmission distance up to 1.2km; (optional);
10.Language can be selected, there are two models in Chinese and English;
11.The parameters are convenient to set up, can be permanently saved, and can save up to three years of historical data;
12.Ultra-low power consumption, a full dry battery performance work can be maintained for at least 3 years;
13.The work mode can be automatically switched, battery-powered, two-wire system;
14.With self-test function, a wealth of self-inspection information, user-friendly maintenance and debugging;
15.With an independent password settings, anti-theft function is reliable, parameters, total reset and calibration can set different levels of passwords, user-friendly management;
