LoRaWAN Ultrasonic Water Meter DN15

<div class="del_item" id="index_1" style="margin: 0px 0px 15px; padding: 0px;"><h3 style="margin-right: 0px; margin-bottom: 15px; margin-left: 0px; padding: 0px;"><span style="font-family: "Open Sans"; font-size: 16px;">The Wireless ultrasonic water meter (LoRa)is intelligent measuring instruments by the flow sensor and calculators. Calculator used the sensor and through the water of time difference to collect temperature differences and sound waves to complete accurate measurement of water flow. It can transmit data through wireless LoRa module. It can provide important application and date for many applications in the pipeline. It has a higher measurement accuracy and is not subject to sand and wear and has a longer service life. This type of water meter, which can detect the time difference caused by the change of velocity when the ultrasonic beam propagates along and against the current in the water, analyze the flow rate of the treated water, and further calculate the flow rate of the treated water. There are no moving parts inside, no current blocking elements, not affected by impurities in water, long service life.</span></h3><div class="adv_ppp" style="color: rgb(51, 51, 51); font-family: Arial, Helvetica, sans-serif;
