High Temperature Ultrasonic Level Sensor

These high-temperature ultrasonic level transmitters are designed to handle extreme temperature environments that ordinary ultrasonic level meters cannot withstand, enabling them to operate stably in conditions where the sensor surface or ambient temperature is as high as 110°C.

  • Model: QYL-U04-H
  • MOQ: 1PCS
  • Payment: Wire transfer/ Credit card/ PayPal
  • Lead Time: 5-7 days
  • OEM/ODM: Available

The maximum temperature resistance of a conventional ultrasonic level monitor is 55°C. Once the temperature is too high, the ultrasonic level sensor will be inaccurate and easily damaged. This high-temperature ultrasonic level meter solves this problem very well.

Principle of ultrasonic level sensorPrinciple

Install height G: ( probe to the height of the tank bottom)
Liquid level H: ( level or material level height)
Air distance L: (probe to test surface area)
Blanking distance C: (a small area below the sensor)
Instrument range d: (generally from zero to the highest plane, only linearly corresponding to output P)

Formula：
1、Ranging：L=S*T/2；  S=331.45+0.61*n℃
2、Level：H=G-L
3、Output： P=H/d*16+4 or P=L/d*16+4 （Note: P output current in mA）

High-temperature ultrasonic level sensors are primarily used in the following applications:

High-temperature process vessels and storage tanks:
Reactors/Anatomists: Vessels used in the chemical, pharmaceutical, and petrochemical industries requiring high-temperature reactions.
High-temperature oil tanks: Tanks for thermal oil, heavy oil, asphalt, and thermal coal tar. Explosion-proof versions are available.
Molten salt tanks: Used for storing molten salt in applications such as solar thermal power generation and industrial thermal energy storage.
Steam condensate recovery tanks/boiler drums: Monitor the level of high-temperature condensate or boiler saturated water.

High-temperature solvent/chemical tanks:
Store chemicals that must remain liquid at high temperatures.
Food and beverage processing (special applications):
High-temperature sterilisation equipment.
Storage tanks for viscous liquids such as syrup and chocolate that require high-temperature processing, storage, and transportation.
Storage tanks are used in pasteurisation or UHT (ultra-high temperature) processes.

Environmental Engineering:
High-temperature wastewater treatment tanks or evaporation tanks (e.g., high-temperature evaporation treatment of industrial high-salinity wastewater).
