LoRaWAN Ultrasonic Water Meter DN15
KES 15,000.00
- Stock: In Stock
- Model: DN20
- SKU: 3308
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.
You can use this by designing your own gateway for a wide range of real life application solutions using a wide variety of LoRA Gateway that we have
