Huaheng instrument realizes from scratch in the core technology, continuously improves the accuracy of industrial automation instruments, instrument performance standard benchmarking international technology, completes product iteration and upgrading, and meets the personalized customization of user needs. Since then, it has been widely used in all kinds of pressure transmitters and liquid level (boundary transmitter manufacturer, flowmeter, temperature sensor and multi parameter transmitter), with complete product measurement qualification and explosion-proof qualification. The whole production system has passed ISO9000 quality certification system certification.
The principle and function of 3151 intelligent double flange liquid level meter. When measuring corrosive or crystalline particles, as well as high viscosity, easy to condense 2113 solid and other media, in order to solve the problem of corrosion or blockage of impulse pipeline, flange of flange type differential pressure transmitter transmitter can be directly connected with 5261 flange on the vessel as the measuring head 1 (metal capsule) of 4102 sensitive elements ）It is connected with the measuring chamber of the transmitter through capillary 2, and filled with silicone oil in the closed system composed of capsule, capillary and measuring chamber. As a pressure medium, it plays the role of isolating the transmitter from the measured medium.
It depends on the size of the hole reserved in the installation position and the size of the reverse installation flange.
另外要看 前端伸入罐中的 部分直径多大。
In addition, it depends on the diameter of the part that the front end extends into the tank.
It is common to install the capacitance liquid level meter with thread but less flange.
According to the operation principle of differential pressure liquid level transmitter:
When the liquid level is measured by double flange with capillary, the installation position (height) of the liquid level gauge has no influence on the measurement;
When measuring the liquid level with single flange with capillary, the installation position (height) of the liquid level gauge is the same as the lower interface, which can avoid the trouble of migration. If the height is not equal to the height, the migration shall be carried out once before the installation and feeding, and the zero position can be aligned
When only one flange is used to measure the liquid level, only two flanges need to be placed at the same height, and the installation position (height) of the liquid level gauge has no effect on the measurement;
Note: the above "installation position has no effect on measurement" is only theoretical. In fact, when the height difference between two flanges or the height difference between a single flange and the transmitter causes the liquid column pressure in the capillary to exceed the measuring range, some liquid level meters will malfunction, which is related to the manufacturing level of the transmitter
At present, our company has three technical strength, one is the fully isolated intelligent circuit processing unit technology, the other is the manufacturing technology of metal capacitance sensor, and the third is the multi parameter technology of the whole series of throttling devices.
With its own sensor and intelligent circuit board core technology, Huaheng transmitter manufacturers can extend and transform the core technology at low cost according to customer requirements to achieve personalized product customization. The main products are smart (SMART) series pressure transmitter, multi parameter transmitter, flowmeter, temperature sensor and level (liquid level transmitter manufacturer, which provides high performance price ratio industrial automatic transmitter manufacturer products for China's power, petroleum, chemical, metallurgical, cement, mining and other industries
