Product Description
The series of YHLW-Y liquid turbine flowmeters are a kind of velocity flowmeter with features of high acuracy, better repeatability, simple structure, less pressure loss and easy maintainance. They are widely used to measure the volume flow of MID- and low-viscosity liquid in closed tubes in the areas of petroleum, chemical industry, water supply, and paper making, etc.
Main Features: Characteristics
1. High acuracy, normal: ± 1%R, ± 0.5%R, high-acuracy: ± 0.2%R
2. Better repeatability, short-term repeatability: 0.05%~0.2%
3. Flowmeter factor nonlinearity compensated intelligently, field modification supported
4. Wide range of caliber, MID- and large-caliber 1: 20, small caliber 1: 10
5. Compact and simpe structure, easy installation and maintenance, better circulating capacity
