1. Features:
ultrasonic smart water meter is a newly developed product with low cost, high measurement, high accuracy, low power consumption, stability and reliability. It complies with ISO4064-2014, GB/T778-2018 and other standards and is based on ultrasonic time difference measurement technology .
This type of industrial water meter has dual channels and four channels and is highly integrated. It has many advantages such as wider measurement range, ultra-low power consumption, stable and reliable performance, etc. All components of this product reach IP68 protection level and can be used in various harsh environments. It is widely used in urban water supply, water resources management, agricultural irrigation, landscaping, and industrial ultrasonic instruments. It is a major technological innovation in the field of water conservancy technical measures.

6.The water meter is calibrated using the constant current method:
When our products are produced, all flow meters are calibrated one-on-one.
At the same time, the cumulative flow rate is measured. Different calibration methods may cause errors. If the start-stop method is used to calibrate equipment, errors may occur. Use the method of prolonging the calibration time when starting and stopping to calibrate the instrument, and ensure that the duration of each start time should be at least more than 60 seconds. The less time it takes to calibrate, the greater the error will be.
7. RFQ:
1. Q: What is the difference between industrial ultrasonic water meters and household water meters?
A: It has better stability, long service life, can be measured in complex environments, has higher measurement accuracy (accuracy: level 2), and has a wider range of product pipe diameters (the maximum can be produced to DN500=20").
2. Q: Are you a trader or manufacturer?
A: We are a manufacturer. We have more than 20 years of R&D and manufacturing experience and are one of the suppliers of flow measurement products for the water conservancy department in China.
3. Q: Can we order samples? What is the minimum order quantity?
A: Of course, we have sufficient inventory and can deliver the fastest. Our minimum order quantity is 1PCS.
4. Q: What payment methods do you support?
5.Q: Can I visit your factory?
6.Q: How is the product guaranteed?
A: All products we manufacture have a 24-month warranty. If there are quality problems, we will provide new products for free.
