Industry New Products Overview of ultrasonic gas meter

Ultrasonic gas meter is an efficient and accurate gas flow measurement device that uses ultrasonic technology for flow measurement. Compared with traditional mechanical gas meters, ultrasonic gas meters have higher measurement accuracy, wider measurement range and better stability. The following is a detailed introduction to ultrasonic gas meters.

1. Working principle

The working principle of ultrasonic gas meters is based on the propagation time difference of ultrasonic signals. The specific process is as follows:

Ultrasonic Transmission: The gas meter has a built-in ultrasonic sensor that emits ultrasonic signals.

Signal Propagation: The ultrasonic signal propagates in the gas, and the propagation speed is related to the flow speed of the gas.

Time Measurement: When gas flows, the time it takes for the ultrasonic signal to propagate in the downstream and counter-current directions will be different. By measuring the difference in travel time between these two cases, the flow rate of the gas can be calculated.

Flow Calculation: Calculate the gas flow rate based on the flow rate and the cross-sectional area of the pipe.

2. Advantages

The equipment adopts the principle of ultrasonic waves, with built-in temperature compensation and pressure compensation devices, which are not affected by environmental temperature and have low pressure loss. Compared with traditional instruments, the measurement is more accurate with a resolution of 0.001m3, which can effectively reduce the transmission and distribution differences caused by measurement.

It can intelligently detect gas quality, flow rate, and temperature. When continuous small flow (gas leakage), reverse flow (reverse installation), overcurrent, long-term constant flow (forgetting to turn off gas), long-term no flow, as well as high temperature, water ingress, abnormal disassembly (gas quality changes from gas to air) and other abnormalities are detected within a certain period of time, the valve will automatically close. It can also be linked with gas alarm and intelligent cut-off device to ensure gas safety in all aspects.

Users can recharge remotely through online channels such as apps and web pages, and gas companies can conduct online tiered pricing and charging to achieve remote meter reading. For users, recharging and using are more convenient; For gas companies, there is no need for manual meter reading, which can significantly save human resources, reduce the risk of errors, omissions, and disorderly readings, and improve meter reading accuracy and efficiency.

3. Application scenarios

Ultrasonic gas meters are widely used in:

City Gas Metering: Gas metering for residential and commercial users.

Industrial Gas Monitoring: Monitor gas usage in industrial production.

Energy Management: used in energy management systems to help enterprises optimize energy use.

4. Installation and maintenance

The installation and maintenance of ultrasonic gas meters are also very important:

Installation location: It should be selected in a place with smooth gas flow and avoid installation in elbows, valves, etc. to ensure accurate measurement.

Regular Calibration: Calibrate the gas meter regularly to ensure its measurement accuracy.

Cleaning and Inspection: Check the sensors and circuits regularly to ensure the equipment is working properly.

5. Future development

With the development of intelligence and Internet of Things technology, ultrasonic gas meters will be increasingly integrated with smart metering systems to achieve more efficient energy management and data analysis.

Summarize

Ultrasonic gas meter is an efficient and accurate gas flow measurement device widely used in homes, industries and commercial areas. Its high precision, wide range and no mechanical wear make it an important choice for modern gas metering. Correct installation and maintenance are key to ensuring long-term stable operation.
