Turbine Flowmeter Product Overview
LWGY series turbine flowmeter is a new generation of turbine flowmeter which is optimized by absorbing advanced technology of domestic and international flow instruments and has simple structure, light weight, high accuracy, good reproducibility, sensitive response, convenient installation and maintenance, etc. In the measurement of closed pipes, it has no corrosion with stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3, hard alloy, and has no impurities such as fibers and particles. At working temperature, liquids with a kinematic viscosity of less than 5 × 10-6m² / s have a kinematic viscosity of 5 × 10-6m² / s liquid, which can be used after the liquid calibration of the flowmeter. If it is matched with a display instrument with special functions, it can also perform quantitative control and over-alarm. It is an ideal instrument for flow measurement and energy saving.
Product Features of Turbine Flowmeter

  • High accuracy, generally up to ± 1% R, ± 0.5% R, high accuracy type can reach ± 0.2% R;
  • Good repeatability, short-term repeatability can reach 0.05% ~ 0.2%, it is precisely because of good repeatability, such as regular calibration or online calibration can get very high accuracy, is the preferred flowmeter in trade settlement;
  • Output pulse frequency signal, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability;
  • Can get very high frequency signal (3 ~ 4kHz), strong signal resolution;
  • Range of models, medium and large caliber up to 1:20, small caliber up to 1:10;
  • Compact and lightweight structure, convenient installation and maintenance, and large circulation capacity;
  • Suitable for high pressure measurement, no need to make holes in the meter body, easy to be made into high voltage instruments;
  • There are many types of special-purpose sensors, which can be designed as various types of special-purpose sensors according to the special needs of users, such as low-temperature type, two-way type, downhole type, mixed sand type, etc .;
  • Can be made into a plug-in type, suitable for large-caliber measurement, small pressure loss, low price, can be continuously removed, convenient installation and maintenance.
