Construction of Portable Pressure Water Level Gauge

Description :

　　Pressure type water level gauges are widely used for hydrological data monitoring in various complex environments, such as groundwater hydrological data monitoring, real-time monitoring of reservoir dam hydrology, monitoring of lake surface runoff water level, unmanned hydrological monitoring, tank level monitoring, and on-site liquid level monitoring of industrial control systems, due to their high precision, multifunctionality, and low power consumption characteristics.

　　Functional characteristics of pressure type water level gauge

　　1. Good stability, with a long-term stability of 0.1% FS/year at full and zero positions. Within the compensation temperature range of 0-70 ℃, the temperature drift is less than 0.1% FS, and within the entire allowable operating temperature range, it is less than 0.3% FS.

　　2. Equipped with reverse protection and current limiting protection circuits, the transmitter will not be damaged if the positive and negative poles are reversed during installation. In case of abnormalities, the transmitter will automatically limit the current to within 35MA.

　　3. Solid state structure, no movable parts, high reliability, long service life.

　　4. Easy to install, simple structure, economical and durable.

　　The pressure type liquid level gauge adopts the principle of static pressure measurement. When the liquid level transmitter is put into a certain depth of the measured liquid, the sensor is subjected to pressure on the liquid surface. At the same time, the pressure of the liquid is introduced into the positive pressure chamber of the sensor through the gas guiding stainless steel. Then, the atmospheric pressure Po on the liquid surface is connected to the negative pressure chamber of the sensor to offset the Po on the back of the sensor, so that the pressure measured by the sensor is: ρ. g.H. By measuring the pressure P, the depth of the liquid level can be obtained.

　　Pressure type water level and temperature sensor:

　　◆ Data collection: It has the function of collecting water level, water temperature, internal battery power, time, etc., and supports various high-precision pressure type water level sensors

　　◆ Data storage and transmission: With built-in storage function, it can store up to 50000 pieces of data, and the data can be transmitted to telemetry terminal devices with high accuracy

　　Sensor management: Sensors come with built-in protocols, support direct interaction with computers, configurable collection time, and can read data stored internally

　　◆ Power supply: Internal and external dual power supply mode, which can be powered by internal batteries or external power sources. The dual power supply automatically switches and has power reverse protection function
