4. Schematic Diagram of Structure of Float Level Meter

DLZ-300 DIGITAL DISPLAY LEVEL METER (K SERIES)

1.

 

Product Overview

The DLZ-300 digital display level meter developed by our company doesn't need any external 
power, and the built-in lithium battery can supply power for more than three years. It is applicable 
to accurate continuous level measurement of liquid nitrogen stored in 0-0.6MPa low-temperature 
container and it has the incomparable technical performance. The data of the digital display level 
meter can be collected and uploaded by radio to 800N and uploaded to 

MRC

 big data cloud 

platform via GPRS or WiFI. It has the advantages such as simple use, wide applicability, high 
intelligence, stable measurement without drift, high stability, high reliability, tight and waterproof 
structure and not requiring regular maintenance and recalibration.

Extension spring

Upper ring connecting rod

Lower ring connecting rod

Measuring rod

Power supply: 3.6V lithium battery power supply, average working current: about 15uA

Effective liquid level measuring range of sensor: 200mm-1000mm

 

Diameter of sensor rod: Φ12mm

Operating humidity range: relative humidity: 0~80%

 

Measuring accuracy: ±1%

 

Working pressure: 0-0.6MPa

 

Measuring medium: liquid nitrogen

Sleeve the PTFE flat seal gasket into the sensor and then wrap M18 connecting thread with

Teflon tape and screw it into the container.

In installation and use of the sensor, if dust, scrap iron, water and other foreign matters enter

into the inner and outer stages of the sensor, they will influence the normal work of the sensor.

 

There is cabling in the sensor and the level meter shall not be disassembled or assembled

privately.
