Turbine Flowmeter

Overview
The series Turbine Flow has its simple structure, light weight, high-accuracy, perfect repeatability, sensitivity, easy maintenance and use. It is widely used to measure liquid which has no chemical corrosive reaction with stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and cemented carbide. This kind of measured liquid has no impurities such as fiberand particles. The movement viscosity is lower than 5×10-6m2/s at working temperature. If the viscosity is higher than 5×10-6m2/s, the flowmeter should be calibrated in the liquid before use. It can finish amount control, excess alertandetc if matched with special functional is playing meter. It the ideal meter for flow measuring and energy saving.

Product Characteristics

  • High accuracy, normal type can reach±1%R, ±0.5%R. High accuracy type can reach to ±0.25%R.
  • Excellent repeatability, repeatability in a short time can reach to 0.05%~0.2%,. Because of excellent repeatability, customers can have extremely high accuracy if they often calibrate or calibrate on-line. It is preferred in trade settlement.
  • Output with pulse frequency signal, suitable total flow measuring and computer connection. No zero drift and strong ability in anti-noise.
  • Can acquire very high frequency signal (3~4KHz), strong signal resolution
  • Wide range: middle and large diameter can reach to 1:20, small diameter can reach to 1:10.
  • Compact and light structure, convenience in installation and maintenance, ability of large flow.
  • Suitable to measure in high pressure. No need to open aperture on the meter, so it is easy to make high pressure meter.
  • Many models of dedicated sensors. Can design dedicated sensors of special requirements for customer, such as low temperature type, two-way type, pump type, sand specific type.
  • Can make plug-in type, suitable to large diameter measuring, little pressure loss, low price, can get out without out flow cut off. Convenient in installing and maintaining.
