Jing Chuan JC-LWGY intelligent corrosion proof turbine flowmeter

1 Overview
JC-LWGY Series turbine flowmeter intelligent integration is the use of advanced low-power single-chip microprocessor technology developed turbine flow sensor and display totalizer integration of new smart meters, with double LCD live display, with a compact body, reading intuitive and clear, high reliability, without outside power interference, anti-lightning, obvious low cost advantage. Meter with three meter factor correction coefficient nonlinear intelligent compensation instrument, and can be corrected on-site. High-definition LCD display simultaneously instantaneous flow (four significant figures) and the cumulative flow (8 significant digits, with clear function) All valid data after power for 10 years is not lost class turbine flowmeters are explosion-proof products, explosion-proof grade: ExdIIBT6. For lubricant oil. Vegetable oil Diesel Oil. And other oil products ..........
Class turbine flowmeter in accordance with power supply, the availability of remote signal output can be divided into LWGY- • B-type and LWGY- • C type.
JC-LWGY- • B type: power supply with 3.2V10AH lithium battery (continuous operation for more than 4 years); no signal output.
JC-LWGY- • C Type: power supply with 24VDC external power supply, the output of a standard two-wire 4-20mA current signal, and depending on the site needs, increase the RS485 or HART communication.
2 .Features
n High accuracy, usually up to ± 1% R, ± 0.5% R, high-precision up to ± 0.2% R;
n Repeatability, short-term repeatability of up to 0.05% to 0.2%, it is due to good reproducibility, such as frequent calibration or online high accuracy calibration available in the trade settlement is the preferred flow meter;
n With three meter factor correction; nonlinear intelligent compensation instrument coefficient; and conduct on-site correction;
n All valid data after power for 10 years is not lost;
n Wide range of degrees, medium and large caliber up to 1:20, small caliber 1:10;
n Compact and lightweight; easy installation and maintenance; large flow capacity;
n Suitable for high pressure measurement; you do not have openings on the meter body; Yi made of high-pressure type instrument;
n Special type of sensor types and more; can be designed for all kinds of special-type sensor according to the special needs; for example, low temperature; bidirectional type; underground type; sand and other special type
n Insertion can be made; for large diameter measurement; pressure loss; low price; do not remove the circuit breaker; for easy installation and maintenance;
