Today, I will introduce a patent for the invention of a national invention - a remote water meter. The patent was applied by Tianjin Zhongtian Electronic Development Co., Ltd. and was authorized to be announced on May 29, 2018.
DescriptionThe invention relates to the field of water meter devices, in particular to a remote water meter.
Background of the inventionAs a measuring instrument, water meters are mostly the cumulative flow measurement of water. Generally divided into two types, volumetric water meter and speed water meter, using the direct mechanical movement process of the active wall volume measuring chamber or the action of the water flow velocity on the wing wheel to calculate the flow volume of the water flowing through the tap water pipe. The water meters are installed at the water inlet end of each user's house door. The traditional water meter requires the staff to observe the records one by one, which is a waste of time; in order to solve the above problems, the collection unit, the short-range communication unit and related are set in the water meter. The signal processing unit sends the water meter readings to the staff's handheld terminal, so that the staff can batchly obtain the water meter readings.
Nowadays, the method is to add a small magnet to the pointer of the original old water meter, and a magnetic sensor and an external acquisition circuit board are added inside the water meter, and the sensor is connected to the external acquisition circuit board through the wire, and the The number of turns of the pointer is detected to achieve the purpose of measuring the amount of water. Since the above-mentioned circuit component is disposed inside the water meter, the water meter needs to be waterproofed, which undoubtedly increases the price of the water meter; and the circuit board part and the sensor part are wearing parts, and the entire water meter needs to be opened for repair during maintenance. It is even necessary to completely replace the water meter, which wastes manpower and material resources and wastes materials. To this end, in order to solve the above problems, the sensor is currently attached to the transparent glass on the dial. This structure has the disadvantage that the reading will be blocked and the reading is difficult.
Summary of the inventionIn order to overcome the deficiencies of the above technology, the present invention provides a remote water meter capable of clearly reading the meter.
The figure is an exploded view of the invention
In order to achieve the above object, the technical solution adopted by the present invention is: a remote water meter, which comprises: a jacket, an inner sleeve, a sensor fixing plate, a sensor fixing seat, a sensor, and the sensor is installed in the sensor fixing seat, and the sensor is fixed. The seat is fixed in the sensor fixing plate, the sensor fixing plate enters into the outer casing from the bottom of the outer casing and is locked to the upper part of the outer casing, and the inner sleeve is pressed into the outer casing from the bottom of the outer casing, and a card table is arranged on the inner wall of the bottom of the outer casing. The card is clamped to the bottom of the inner sleeve.
A cover plate is hinged on the outer casing. A sensor cover is provided on the sensor mount.
The utility model has the beneficial effects that the water meter is compact and easy to assemble compared with the prior art, and only needs to add an end cover to the upper part of the existing water meter, the end cover is the structure of the invention, and the sensor is fixed on the sensor fixing seat. The fixing base is integrally fixed on the sensor fixing plate. Since the sensor is mounted on one side of the sensor fixing plate, the number is not blocked, and the device is easily fixed on the upper part of the water meter, and the installation is convenient.
Marine High Temperature Pressure Sensor
Product overview high temperature pressure sensor is a signal measuring element. The measured medium pressure is transmitted to the sensor through the heat dissipation structure on the transmitter. The high-precision signal processing circuit is located in the stainless steel shell to convert the sensor output signal into standard output signal. The whole product has undergone strict testing and aging screening of components, semi-finished products and finished products, with stable and reliable performance, so that the product can work stably for a long time when used for pressure measurement of high-temperature medium. Product features 1. 316L stainless steel isolation diaphragm structure 2. Imported high temperature resistant chip 3. Wide applicable medium temperature range 4. Strong anti-interference and good long-term stability 5. Direct contact with high-temperature medium to improve pressure response frequency 6. Provide rich pressure range of low pressure, medium pressure and high pressure
