1, LWY series liquid turbine flowmeter
LWY series of turbine flowmeter is to draw on the domestic and foreignadvanced technology through the optimization design of the flow meter,has the advantages of simple structure, compact, high accuracy, good reproducibility, sensitive reaction, installation and maintenance of a new generation of turbine flow meter is convenient wait for a characteristic,widely used in water, diesel, methanol, no impurities, no strong corrosive liquid, if the display instrument with special functions, can be used for quantitative control, overload alarm, is the ideal energy flow measurement and instrumentation.
2, the characteristics of the LWY product
1) maintenance high precision, generally up to ± 1%R,± 0.5%R, high precision is up to ± 0.2%R;
2) with good reproducibility, short-term repeatability can reach 0.05% ~ 0.2%, it is because of good repeatability, such as regular calibration orcalibration can obtain high accuracy,
Trade settlement in the meter is preferred;
3) output pulse frequency signal, to measure the amount and is connected with the computer, no zero drift, strong anti-interference ability;
4) can obtain very high frequency signal (3 ~ 4kHz), signal discrimination;
5) range, large diameter up to 1:20, the small diameter of 1:10;
6) has the advantage of compact structure, convenient installation and maintenance, large flow capacity;
7) for the high pressure measurement, the instrument body withoutopening, easily made high pressure type instrument;
8) special sensor types, according to the special needs of the user designfor all kinds of special type sensors, for example temperature, bidirectional,underground type, special type sand mixing
9) can be made into type, suitable for large diameter measurement, small pressure loss, low price, can not flow out, installation.
