I. Product Overview
The metal tube rotator flowmeter is a reference flow measuring liquid and gas continuously in a closed pipe by variable area measurement principle. The local display and intelligent remote transmission support multiple output protocols, providing users with a wide choice of space. In addition, the instrument adopts advanced 16 bit microprocessor and high quality industrial components, which ensures the good performance of flowmeters in various application places.
The metal tube rotator flowmeter is based on the principle of variable area measurement, which is used to continuously measure the reference flow of liquid and gas in closed pipelines. It can be used to detect the flow rate of liquid, gas and steam, especially for medium flow measurement with low flow rate and small flow rate.
Two. Product application
1. All metal structure, suitable for high temperature, high pressure and strong corrosive medium.
2, can bring data recovery, data is sealed and power failure protection function.
3, suitable for low flow medium flow detection.
4, the range of payment is 10:1, special type 20:1.
5, the requirement for straight section is not high.
6, dual line LCD screen display, with backlight.
7, simultaneous display of instantaneous flow and cumulative flow rate.
