WYZ-1 bubble type water level gauge

1. Overview
WYZ-1 bubble type water level gauge is a high-precision water level sensor developed and developed by our company. The compressed air produced by the piston pump flows through the measuring tube and the bubble chamber, and enters the measured water body. The static pressure in the measuring tube is proportional to the height of the water level in the bubble chamber. The bubble type water gauge has successively measured the atmospheric pressure and bubble pressure, taking the difference between the two signals, calculated the water level above the bubble chamber.
The characteristics of bubble type water level gauge has the advantages of high accuracy, high reliability, high intelligent, free, free gas logging, free maintenance, anti vibration, long service life, especially suitable for the flow of water, large and small rivers, reservoirs, or serious water pollution and corrosion of industrial wastewater or well logging construction inconvenience expensive the occasion, such as water conservancy, hydrology, marine, groundwater dam, petroleum, chemical industry, sewage treatment plant, the city drainage pumping station monitoring.

2, functional features
Non contact measurement, high precision, good stability, convenient maintenance;
It is easy to install without logging, and is not affected by floating objects on the water surface;
With zero correction function, the zero drift error can be eliminated completely;
Through the external temperature sensor, can effectively compensate the liquid specific gravity by the influence of temperature change;
It has analog output and digital communication interface, which is convenient for users;
Wide voltage design, with reverse connection protection, over-voltage over-current protection and lightning surge absorption capacity;
LCD display and keyboard input, intuitive display of instant water level, flexible operation;
Automatic cleaning function, to ensure the smooth flow of the trachea;
10 thousand recording records are stored in a loop;
Modbus protocol is used to connect with all kinds of data acquisition devices.
