4-20mA Good Quality Intelligent Turbine Flow Meter for Gas (JH-LWQ)

Turbine gas flow meter is widely used in pharmaceutical, food, beverage and other industries, as measured ingredients, control, finished filling and other uses of flow measurement instruments. The instrument case is made of stainless steel (316L) made part of the movement to use special materials, with good anti-corrosion, anti-rust capability. Entire table structure break through the traditional process, using advanced structural optimization design, greatly improving the accuracy and repeatability of the instrument. Turbine flowmeter designed for the pharmaceutical, beverage industry, the use of fast-loading connection structure for easy cleaning. HL-LWS Series Hygienic turbine flowmeter has reached the international standard of similar products, the health industry is an ideal instrument.
 
Applications:
LWQ gas turbine flowmeter is high accuracy meter which can be widely used in the fields of air, natural gas etc.
 
Features:
-High accuracy, usually reach ± 1%R, ± 5%R, or even reach ± 0.2%R for high-precision type
-Good repeatable and repeatability, can reach 0.05%-0.2% in short term, if regular calibration or online calibration can get an extremely high accuracy, so it is preferred in trade
-Pulse signal output, suitable for total flow measurement and computer connection, no zero drift, strong anti-jamming capability
-High frequency signal (3-4kHz), strong signal resolution
-Wide range, middle and big diameter can reach 1: 20, and small diameter can reach 1: 10
-Compact structure, easy installation and maintenance, strong flow capacity
-Suitable for high pressure measurement. The interface of the instrument doesn't have to be opened, so it can be made to a high pressure instrument easily
It can be customer-tailored according to different sensors, for example, low-temperature type, two-way type, underground type, sand special type, etc
-It can be insert type, suitable for large diameter measurement, little pressure loss, low price, can be taken out in continuous flow, and easy installation and maintenance.
