Electric float level gauge is a liquid level measurement device with many advantages.
working principle:Composed of float, torque tube, sensor and other parts. The float is immersed in the measured liquid, and according to Archimedes' principle, the buoyancy experienced by the float is proportional to the density of the liquid and the volume of the displaced liquid. When the liquid level changes, the buoyancy of the float changes, and its position also changes accordingly. This position change is transmitted to the sensor through the torque tube, and the sensor converts it into an electrical signal output to achieve liquid level measurement.

Installation and wiring precautions:
a. The installation of instruments must be vertical and firm and reliable. If the instrument display is not at zero point after installation, you can follow the software operation instructions to reset and migrate to zero point.
b. During installation, the transmitter should not be subjected to strong vibrations, impacts, or local overheating, especially for the lever hanging on the inner cylinder, which should not swing or be pulled or compressed significantly to avoid damaging the accuracy of the instrument or causing damage to the instrument.
c. Install the inner cylinder correctly and tighten the nut.
d. This instrument does not participate in public welfare experiments such as gas sweeping, airtightness, water pressure, etc. conducted before or after the device is put into operation.
e. After the instrument wiring is completed, the end cap should be tightened to prevent water from entering and damaging the instrument.
f. When the instrument needs to be debugged or repaired, the electrical parameters and structure must not be changed, especially on areas coated with red paint. It is strictly prohibited to twist them forcefully to avoid damaging the instrument.
g. The instrument casing should be well grounded.
h. When the measured medium fluctuates greatly, a surge tube is required to measure the liquid level with a float.
Applicable industries and sites:
Petrochemical industry: commonly used to measure the liquid level of high-temperature, high-pressure, and high viscosity liquids in petrochemical production, such as oil tanks, reactors, separators, and other equipment in refineries and chemical plants.
Power industry: It can be used for measuring high temperature and high pressure liquid levels such as boiler drum water level and deaerator water level in thermal power plants, and also has applications in special occasions such as reactor coolant level in nuclear power plants.
Metallurgical industry: measurement of high temperature molten metal liquid level in steelmaking, ironmaking and other processes.
Food and beverage industry: suitable for measuring high viscosity liquids such as syrup and jam.
Selection suggestion:
Measurement range: Select the appropriate model based on the actual liquid level measurement range to ensure that the requirements are met.
Work pressure and temperature: Understand the pressure and temperature of the measurement environment, choose a level gauge that can adapt, and when the pressure and temperature are high, choose a model that is resistant to high temperature and high pressure.
Medium characteristics: Considering the corrosiveness, viscosity, and other properties of the medium, corrosion-resistant level gauges are selected for corrosive media, and suitable models are selected for high viscosity media.
