Tri-Clamp Turbine Meters Water Flow Meter
The clamp-type turbine flowmeter is a new generation of turbine flowmeter with a simple structure, light weight, high accuracy, good reproducibility, sensitive response, convenient installation, maintenance, and use, which is widely used to measure the corrosion of stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al2O3 and hard alloy in closed pipes, and is free of fibers, particles, and other impurities.
Product specifications:
High precision, generally up to ± 1% R, ± 0.5% R, high precision type up to ± 0.2% R;
Good repeatability, short-term repeatability can reach 0.05%~0.2%;
Output pulse frequency signal, suitable for total metering and computer connection, no zero drift, strong anti-interference capability;
A high frequency signal (3-4kHz) can be obtained with strong signal resolution;
Wide range, up to 1:20 for medium and large calibers and 1:10 for small calibers;
Compact and light structure, convenient installation and maintenance, and large circulation capacity;
It is suitable for high voltage measurement. There is no need to open a hole in the meter body, and it is easy to make a high voltage instrument;
There are many types of special sensors, which can be designed as various special sensors according to the special needs of users;
It can be made into a plug-in type, suitable for large diameter measurement, with small pressure loss, low price, and easy installation and maintenance.
