Background

The vertical valve controlled water meter is one integrated valve and water meter, and the valve and the water meter are integrated into one device and combined together in one vertical structure. The design makes the installation simple and convenient, saves space, and makes the operation of valve and water gauge more convenient. The vertical valve control water meter has a valve control function, and can control the opening and closing of water flow through the valve. The user can control the supply of water by operating the valve, so as to realize the adjustment and control of the water flow. Vertical valve controlled water meters are often provided with a function of preventing illegal use. It can prevent unauthorized use of water source by valve control and sealing design, and provide reliability of water resource management.

The ultrasonic water meter has no mechanical rotating parts, so that the ultrasonic water meter cannot be worn during the use process of a user. And the ultrasonic water meter adopts a non-contact measurement mode, and water flow is measured by transmitting ultrasonic signals and receiving echoes. This means that it does not need to physically contact the water flow, does not affect the water quality, and reduces the likelihood of wear and clogging. And moreover, the ultrasonic water meter adopts an accurate ultrasonic measurement technology, so that the water flow can be accurately measured in real time. It can provide high precision data suitable for applications requiring accurate measurements, such as billing and traffic monitoring. The ultrasonic water meter has a large measuring range. The device can be suitable for pipelines with different sizes and flow rates, and can effectively measure from small flow rate to large flow rate. This allows flexibility in the ultrasonic meter in various application scenarios. The design of the ultrasonic water meter causes less pressure loss when water flows through, and ensures the stability of the water flow and the accuracy of flow measurement.

The valve-controlled water meter has the demand that some clients provide the controllable valve opening and closing degree, so that the water meter is arranged in the user's home, the user can be guaranteed to reduce the water consumption when the user is defaulted, the reminding function is achieved, the user can be guaranteed not to influence basic life due to complete water interruption caused by complete closing of the valve, and therefore information feedback is required to the opening and closing degree of the valve. When the user is less in arrears, the valve is closed in a small amount to reduce the flow, so that the minimum basic water consumption requirement of the user is ensured, and the user can be urged to pay timely and early to a certain extent so as to obtain the right of fully opening the valve to obtain the water with large flow. The valve of the traditional valve-controlled water meter only has two states of full opening and full closing, and the state of the opening and closing degree of the valve cannot be fed back and controlled by information. In this case, there is a great need for a vertical valve-controlled water meter with a certain valve opening feedback and adjustment function.
