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 feld 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 fow, 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 rectifcation structure can better improve the disturbance of the fow feld;
9. Both the metering and main control modules are designed independently, without mutual interference and good reliability;
10. Strong media adaptability, automatic correction.
