Specifications

Intelligent multi parameter transmitter for flow measurement and display
Main Features

1. LCD dot matrix display, Instant flow rate and totalized flow and temperature and pressure value can be displayed simultaneously with high-brightness backlight, simple and clear operation.

2.the 16 bit microcomputer chip has the advantages of high integration, small size, good performance and strong function of the whole machine.No mechanical movable parts, stable and reliable, long life, long-term operation without special maintenance.

3.Easy to use: Only set several parameters by software or the device key, It can be used to measure the gas, liquid or steam of various instrument caliber.

4.Can be matched with various types of differential pressure flow sensor (such as hole plate, V cone, Annubar, pipe pressure sensor arithmetic);

5.with excellent nonlinear correction function, greatly improve the instrument linear, range ratio 1:100.

6.the center of the sensing unit adopts high precision silicon technology leading, platinum level accuracy + 0.075%, designed to protect the double diaphragm overload, one-way overvoltage is up to 40MPa, static performance, static optimal error can be controlled in less than 0.05%/10MPa.

7.An excellent temperature compensation algorithm is used to minimize the influence of temperature on the measurement, and the optimal control is at + 0.04%/10K..

8. Intelligent flow meter flow probe, microprocessor, pressure and temperature sensor(Pt100 or Pt1000) in one, take the built-in combination, make the structure more compact, can flow, pressure and temperature measurement of fluid directly, and real-time automatic tracking compensation and compression factor correction.

9. with EEPROM technology, the parameter setting is convenient and can be permanently saved, and the longest historical data can be saved for one year.

10. It has self checking function, rich self checking information, convenient for user to overhaul and debug.

11. with independent password settings, anti-theft function is reliable, parameters, total clearance and calibration can be set at different levels of passwords, user-friendly management;

12. the converter can output frequency pulse, 4 ~ 20mA analog signal, and has RS485 interface, can be directly connected with the microcomputer

13. the converter shows 360 degree rotation, and it is easy to install and use

14. the power consumption of the whole machine is low, the external power supply and battery power supply can be supplied, and the power supply mode can be switched automatically.
