Manufacturing method of weighing method water meter verification device system

The weighing water meter verification device directly affects the accuracy of the water supply company's measurement and settlement and the interests of consumers.Smart meters, IC card water meters and other new water meters with functions of charging and automatic water cutoff have become commonly used water meters by industry and residents.Water meter verification device by weighing methodIt is used to complete the verification of measuring instruments to ensure accurate and reliable measurement in the water supply industry.At present, the existing water meter verification equipment cannot perform quick and easy-to-operate verification of the automatic water cut-off function of the water meter. Then, let's learn about the production method of the weighing method water meter verification device system!

Technical realization elements of weighing method water meter verification device:

The purpose of this article is to provide a water meter detection device and water meter detection system, which solves the problems of low water meter detection efficiency and low utilization rate of water supply devices, and can use one water supply device to supply water to multiple water meter detection channels for water meter detection, and can be used in various Multiple water meters are installed on the water meter detection channel.

The weighing method water meter verification device includes a water supply device, a first water meter detection channel, a second water meter detection channel, a water meter water supply detection device and a water meter outlet water detection device.Both m and n are integers of 1 or more.Both the first water meter detection channel and the second water meter detection channel are connected to the water supply device, the first water meter detection channel can be installed with m water meters, and the water meter outlet detection device is used to detect the actual water output of each of the m water meters and/or n water meters.The second water meter detection channel can be installed with n water meters. The water meter water inlet detection device is used to detect the measured water inflow of m water meters and/or n water meters respectively. By comparing the metered water supply and actual water output of each water meter, it can be expressed The verification result of whether the cumulative flow rate of each water meter is correct.

The water supply system of the gravimetric water meter verification device includes a water tank, a water pump and a buffer tank, and the water pump is connected with the water tank and the buffer tank.The water tank is used to store test water, the water pump is used to pressurize the water in the water tank, and the surge tank is used to balance the water volume and pressure in the pipeline.

Water meter verification device by weighing methodThe water inlet part is connected with the first flow controller and the second flow controller, and the actual water volume data acquirer is set according to the measurement method in cooperation with the water inlet part.The water outlet part can be opened and closed, and the water outlet detection device of the water meter includes a water inlet part, an actual water quantity data acquirer and a water outlet part.Its one end is connected with the water inlet part, and the other end is connected with the water tank.

When the weighing method water meter verification device is performing water meter verification, install the water meter on the first and/or second water meter detection channel, start the water meter verification device after adjusting the valve, and store the water for measurement in the water tank through the water pump to the water meter into the water detection device Or after flowing through the second water meter load channel, the water meter inlet detection device obtains the metered water inlet of the water meter through different flow controls, and then the water flows into the water meter outlet detector to obtain the actual water outlet of the water meter, and calculates the metered inlet of the water meter by comparing different flow rates. Determine whether the cumulative flow of each water meter is correct or not. After detecting the cumulative flow of the water meter, the water meter verification system can monitor and control the water meter verification device to complete the water meter verification.In the embodiment of this paper, the shared water supply device in multiple water meter detection passages provided with open circuit detection tubes ensures the kinetic energy utilization rate of the water supply device, and utilizes the first water meter placement passage and the second water meter placement passage respectively. A cut-off detection tube and a second cut-off detection tube detect the cut-off function of the water meter.In addition, the water meter verification device can realize rapid verification of the circuit breaker function of the water meter.In the spirit and principle of the product, the above description is only a preferred embodiment of the product, and is not intended to limit the product. For those skilled in the art, various modifications and changes can be made to the product.Any modification, equivalent replacement, improvement, etc. must be included in the scope of protection of this product.
