[Patent patents] Ultrasonic cold water meter and heat meter base meter calibration device

Content Description

The utility model belongs to the technical field of an ultrasonic measuring device, in particular to a device for calibrating an ultrasonic cold water meter and a heat meter.

Background of the invention

In the field of water meters, ultrasonic cold water meters and heat meters have been widely used in the industry due to their high accuracy, good stability, and no drive structure. As the core part of the ultrasonic cold water meter and the heat meter, the importance of the parameter calibration is self-evident, but there is no device that specifically calibrates the ultrasonic water meter and the heat meter base meter in the industry.

The successful development of the intelligent ultrasonic cold water meter is a breakthrough compared to the traditional mechanical water meter. It rewrites the technical pattern of the traditional water meter and successfully realizes full-electronic high-precision detection of water consumption and non-destructive real-time transmission of water data. It lays the foundation for the construction of "Smart Water Network" in today's increasingly poor water resources and provides excellent new products for the water network's perception layer. The "UW-type intelligent ultrasonic cold water meter" developed by Chongqing Weidao Instrument Manufacturing Co., Ltd. was formally obtained by the Chongqing Municipal Bureau of Quality and Technical Supervision "type approval certificate for measuring instruments."

Ultrasonic water meter is mainly used for large diameter measurement above DN40, because the current cost is relatively high. It has high precision, wide range ratio, and small flow metering accuracy, which is suitable for those occasions with large tables and small flow (should take into account fire fighting water). Can restore a lot of water fee losses to the water company. Another feature is that it is very easy to implement wireless remote transmission. Instant traffic and accumulated traffic can be easily transmitted to your office, so that you can understand the user's water situation while sitting at home. Especially suitable for those who use water.

The heat meter is also called the heat meter. In the north, it is called the heating meter. In fact, it can measure the amount of heat or cold. The basic structure is three parts: the metering medium flow meter (also called the base meter), the temperature sensor, and the calculation and recording heat energy calculation The heat meter made with a hot water meter is called the base meter; the heat meter now has a variety of ultrasonic, electromagnetic and mechanical types.

Summary of the Invention

The purpose of the utility model is to provide a calibration device for the ultrasonic cold water meter and the heat meter base table, and a base meter calibration device is designed for the ultrasonic cold water meter or the heat meter, and the base meter parameter is measured by the base meter calibration device, and the Comparison of standard parameters, resulting in corrections.

The utility model is a structural schematic diagram of an ultrasonic ultrasonic water meter and a heat meter base metering device

In order to solve the above technical problems, the utility model is implemented by the following technical solutions: The utility model is a calibration device for an ultrasonic cold water meter and a heat meter, including a silent submersible pump, a PPR water separator, a PPR elbow, PPR pipe, PPR tee, plastic water tank, solenoid valve, watch parts, electromagnetic valve adopts waterproof electromagnetic valve, the plastic water tank is fixed with a bracket; the silent submersible pump is fixed inside the plastic water tank; the plastic water tank is The external fixed time controller and temperature transmitter; the time controller is used to control the switch of the waterproof electromagnetic valve; the temperature transmitter is used for temperature acquisition, the PPR pipe, PPR water separator, PPR elbow and PPR tee The tubes are connected and form a loop; wherein, the PPR water separator is fixed on a bracket; the watch pieces are fixed on the PPR water separator, and each watch piece is matched with a wireless module. One end of the electromagnetic valve is connected with a PPR tee; the other end of the electromagnetic valve is connected with a hose, and the waterproof electromagnetic valve is used to control the flow of water.

Further, the PPR water separator 3 is connected with a plurality of pipe joints; the watch piece is connected to the PPR water separator 3 through a pipe joint; the angle between the pipe joint and the surface on which the PPR water separator 3 is located is The range of 0-90° causes the PPR manifold 3 to be tilted to avoid splashing. The watch includes an ultrasonic cold water meter or a heat meter. The PPR water trap, PPR elbow, PPR pipe, PPR tee, PPR pipe, PPR elbow, PPR water trap, PPR elbow, PPR pipe, PPR tee, PPR pipe, PPR elbow The connection forms a ring structure.

The utility model has the following beneficial effects: The utility model designs a base table calibration device for an ultrasonic cold water water meter or a heat meter, measures the base table parameters through a base table calibration device, and compares with a standard parameter to obtain a correction value, which is accurate and effective. The correction parameters of the ultrasonic cold water meter and the heat meter base table are obtained, which have a good measurement effect, convenient installation, and convenience.

Of course, implementing any of the products of the present invention does not necessarily need to achieve all the advantages described above at the same time.
