What is a remote water meter?
The remote water meter is composed of an ordinary sending water meter and an electronic acquisition module. The electronic module completes signal acquisition, data processing, storage and uploads the data to the repeater or hand-held meter reading device through the communication line. The meter body adopts an integrated design, which can record and save the user's water consumption in real time. Each water meter has a unique code. When the smart water meter receives the meter reading instruction, it can immediately upload the water meter data to the management system. Based on ordinary mechanical cold and hot water meters, coupled with the remote transmission system, the main control parameters selected for the water meter part are flow rate, common flow rate, overload flow rate, minimum flow rate, boundary flow rate, nominal pressure, and maximum allowable working pressure. , pressure loss, etc.
Principle of remote water meter
The shell of the remote water meter adopts fully sealed structure design and engineering installation connection sealing technology. Its specially designed water meter connector not only eliminates the problem of multi-core water leakage, but also facilitates the replacement of the water meter. It can run stably for a long time in an environment of 2 meters underwater, thus eliminating the harm of water. In the base meter of the remote water meter, only an impeller with a magnet on the top rotates, and there is no gear transmission damping. The shaft of the impeller is made of stainless steel, and the shaft sleeve is made of bronze. Sensitive and wear-resistant, after testing 10,000 tons of rated flow water flows through the water meter, the bushing wears only 0.01 mm. When the water flow is small, the one-way valve plate falls under the action of gravity, closes the water inlet valve, and several water inlet grooves in the valve are closed. The water flow can only enter the impeller through a water inlet trough that is directly connected to the water inlet, which not only prevents the disadvantage of the water meter being installed upside down, but also realizes the need of dripping and leaving.
The remote water meter is based on the ordinary mechanical cold and hot water meter, the passive switch direct reading remote water meter is composed of the passive switch direct reading remote water meter and the remote transmission system. The main control parameters selected for the water meter part are: Flow, common flow, overload flow, minimum flow, boundary flow, nominal pressure, maximum allowable working pressure, pressure loss, etc.
