1.Product Description

Intelligent swirl flow meter integrates the functions of flow, temperature and pressure detection, and can automatically compensate the temperature, pressure and compression factors. It is an ideal instrument for gas metering in petroleum, chemical industry, electric power, metallurgy and other industries.

2.Main features

1)No mechanical moving parts, not easy corrosion, stable and reliable, long life, long running without special maintenance;
2)Using 16-bit single chip, high integration, small size, good performance, the whole machine function is strong;
3)Set intelligent flow meter flow sensor, microprocessor, pressure and temperature sensor, adopt built-in combination, make the structure more compact, can directly measure the fluid flow, pressure and temperature, and automatic tracking compensation and real-time compression factor correction;
4)Using characters dot matrix display screen, display digits, more intuitive reading convenient, can be directly display instantaneous flow instandard  condition, the total volume flow, pressure, temperature.
5)Using EEPROM technology, convenient parameter Settings, can be permanent, and can save up to a year of historical data;
6)Converter can output pulse frequency, 4 ~ 20 ma analog signals, with RS485 interface, can be directly with the computer networking, transmission distance of 1.2 km;
7)Physical parameter alarm output more, can choose any one of them by the user;
8)The sensor input pressure and temperature signal, strong interchangeability.
9)Machine low power consumption, can be used in batteries, also can be an external power supply.
