1. Comparison of structure, ultrasonic water meter has no blockage.
Ultrasonic water meter is with reflects the fluid dynamics structure, no straight pipe installation requirements. Mechanical water meters use impeller rotation to measure flow, and the flow resistance device in the pipeline leads to the low flow capacity of mechanical water meters, which is easy to be blocked, and wear is more serious.
2. Compared with the start flow. The start flow of the ultrasonic water meter is very low, which greatly reduces the leakage phenomenon of small flow, so that the water metering loss is reduced to the minimum.
3. Pressure loss comparison. ultrasonic water meter energy saving effect is obvious, ultrasonic water meter low pressure loss, greatly reduce the loss of power consumption, but also reduce the energy consumption of water supply.
4. The smart ultrasonic water meter can judge the flow direction of the fluid, and can measure the positive and negative flow values, and it can measure the flow rate, flow, total flow, record the working time and failure time and other parameters. Mechanical water meters fail to detect reverse installation, resulting in metering losses, providing opportunities for illegal use of water, and can only measure total flow.
5. Meter reading and communication comparison
Most mechanical water meters use the mechanical principle of counting, although there is no power supply requirements, but also the output cannot be configured, cannot achieve data acquisition computer management, wireless meter reading and other new technology applications. The ultrasonic flowmeter of Lanry Instruments uses battery power, can work continuously more than 10 years, and can configure a variety of output: 4-20MA, pulse, RS485-modbus, Lora, NB-Iot, GPRS/GSM meter reading system and wireless M-bus is also ok.
6. Accuracy comparison
Since there are no wear parts in the structure of ultrasonic water meters, the accuracy of ultrasonic water meters will remain unchanged as long as the inner diameter of the pipe is unchanged. Due to the structure of mechanical water meter with easy wear parts, the wear degree will gradually increase with the use of time, resulting in the accuracy of the increase with the increase of time, increase the measurement error. Lanry Instruments ultrasonic water meter is with high accuracy as class one.
