LCQ series wireless remote ultrasonic gas meter (hereinafter
referred to as gas meter) is an ultrasonic gas meter carefully
crafted by our company.High-precision ultrasonic transducers and
advanced software algorithms are used to achieve accurate
measurement, and combined with NB-IoT narrowband IoT communication
technology to realize the gas meter networking function.It meets
the requirements of GB/T39841-2021 "Ultrasonic Gas Meter",
JJG10302007 "Ultrasonic Flow Meter".It has measurement
characteristics such as high precision, strong reliability, wide
range ratio, and good durability. It also has intelligent functions
such as temperature and pressure correction, online monitoring,
meter reading, payment, and price adjustment. The gas meter is
suitable for measuring various non-corrosive gases. It can be
widely used in gas metering of gas users. It is a new generation of
ideal intelligent gas meter that effectively solves the measurement
loss caused by the fact that the range cannot meet the actual needs
and the temperature and pressure changes.
1. The gas meter has high measurement accuracy, adopts segmented flow
coefficient correction, low initial flow rate, and wide measuring
range;
2. Electronic metering, no moving parts, no mechanical loss, good
durability, long service life and low failure rate;
3. It has the characteristics of anti-noise, anti-electromagnetic
ffeld interference, anti-disassembly, and anti-reverse
installation;
4. It has alarm and cut-off functions such as micro-leakage, abnormal
flow, abnormal high temperature, unauthorized meter removal,
constant ffow, etc;
5. Adopt dual power supply design;
6. Encryption algorithm is used for remote communication data to
ensure data security;
7. The gas meter has built-in temperature and pressure sensors, which
can realize volume measurement under working conditions and
standard conditions;
8. The unique rectiffcation structure can better improve the
disturbance of the ffow ffeld;
9. Both the metering and main control modules are designed
independently, without mutual interference and good reliability;
10. Strong media adaptability, automatic correction
