JTLWGY liquid turbine flowmeter

Kind of turbine flowmeter itself does not have on-site display, only traffic signal remote output. Traffic signals can be divided into a pulse signal or current signal (4-20mA); low meter price, high integration, small size, especially for the secondary display device, PLC, DCS and other control systems with the use of computer 1. High accuracy , generally up to ± 1% R, ± 0.5% R, high-precision up to ± 0.2% R 2. repeatable, short-term repeatability of up to 0.05% to 0.2%, it is due to have a good reproducibility, such as frequent calibration or on-line calibration to obtain extremely high accuracy in the trade settlement is the preferred flow meter 3. The output pulse frequency signal, suitable for the total measurement and connected to the computer, no zero drift, anti-interference ability 4. availability of high frequency signals (3-4kHz), resolution and strong signal range width of 5, medium and large caliber up to 1:20, and small caliber 1:10 6. Compact and lightweight structure, easy installation and maintenance, flow capacity 7. The application of coercive measure large, do not have openings on the meter body, easily made the high-pressure type instrument 8. The special sensor types, can be designed for all kinds of special-type sensor according to the special needs, such as low temperature, two-way type, underground type, special type of sand, etc. 9. Insertion can be made for large diameter measurement, pressure loss, low price, time to drying out, easy installation and maintenance technical parameters LWGY- □ N-type sensors: 12 ~ 24VDC power supply, three-wire pulse output, high ≥8V, low ≤0.8V; signal transmission distance ≤1000 meters; LWGY- □ A transmitter: 24VDC power supply, two-wire 4-20mA output signal transmission distance ≤1000 technology Performance: meter diameter and connection 4,6,10,15,20,25,32,40 threaded connections (15,20,25,32,40) 50,65,80,100,125,150,200 use Flanged Accuracy class ± 1% R, ± 0.5% R turndown ratio 1:10; 1:15; 1:20 instruments Material 304, 316 (L) stainless steel measured medium temperature (℃) -20 ~ + 120 ℃ Environmental conditions Temperature -10 ~ + 55 ℃, relative humidity of 5% to 90%, atmospheric pressure 86 ~ 106Kpa output signal pulse frequency signal, low ≤0.8V high ≥8V; 4-20mA DC current signal power supply + 12VDC, + 24VDC (optional) signal transmission lines STVPV3 * 0.3 (three-wire); 2 * 0.3 (two-wire) transmission distance ≤1000m signal line interface Houseman connector proof grade non-hazardous product protection class IP65 2.
