Description
I. Introduction
The intelligent target flowmeter is based on the traditional diaphragm type target flowmeter. The new strain sensor is applied to the target flowmeter. At the same time, the new digital technology and microelectronic technology are applied to process the detected sensing signal into 4 to 20mA signal output which is proportional to the flow rate. Meanwhile, the traditional target flow is displayed by displaying the instantaneous flow and accumulative flow simultaneously through two large liquid crystals. Both structure and performance have been improved significantly. The smart strain target flowmeter is applying for the national patent.
Two, product characteristics
High temperature and high pressure: from -80 to +200, the pressure can reach 10MPa
Suitable for all kinds of caliber: Phi 15 ~ 1500mm
It is suitable for measuring liquid, gas and steam.
Low velocity medium can be measured, and the flow rate can be measured at more than 0.1m/s (the Reynolds number is greater than 1000).
A medium with large viscosity and sediment.
Accurate measurement, high accuracy, up to 0.2% (special order).
The pressure loss is small, which is half of the standard orifice, and the big diameter decreases obviously.
