NB-IoT is a narrowband technology, our company uses modules from communications companies such as mobile or telecommunications companies to directly upload the data in the meter to the server through the communications company’s network and parse the data required by the user.Our company's products support mobile, telecommunications, and China Unicom communication methods. The product will use our company's module by default. Clients can provide their own modules or cards. Overseas users need to provide local operators and APN codes to facilitate debugging.
Products description
The dry-type water meter is not affected by the water suspended impurities because its counting structure is isolated from the water measurement. It ensures the normal operation of the counting and clear readings.Compared with the wet type, the dry type water meter will not cause fogging or condensation under the glass due to the temperature difference between the inside and outside, which will affect the reading of the water meter.
Function feature
1.laddered water price 2.Balance alarm 3.Anti-magnetic interference 4.Automatic valve maintenance 5.Fixed consumption 6.Electric shutoff valve.
Product feature
■ Multi jet, dry rotary vane.
■ Dry magnetic drive, anti-magnetic function, counter vacuum sealed, anti-condensation and atomization, it can keep clear readings in long term, also with a long life.
■ Using high quality materials, not easily damaged in low temperatures and humidity.
■ Since the counter is not immersed in water, it has strong anti-freezing ability and will not be exploded by low-temperature freezing.
■ The measurement accuracy complies with the GB/T778-2018 standard.
■ This series of water meters has strong permeability and is easy to replace.
■ It can be added the remote pulse output function.
■ Optional Case: copper case、nylon case.
