UL30 – Explosion Proof Ultrasonic Level Sensor
The UL30 Explosion Proof Ultrasonic Level Sensor provides precise, non-contact liquid level measurement in hazardous environments. With a measurement range of 5 to 60 m, it delivers reliable readings for tanks and process vessels in the oil, gas, and chemical industries.
Typical Applications:
-
Petrochemical storage tanks
-
Oil refinery process vessels
-
Chemical manufacturing plants
-
Hazardous waste storage facilities
-
Gasoline dispensing stations
-
Fuel storage and distribution systems
-
Offshore and marine applications
Description
The UL30 is a specially designed ultrasonic level sensor with explosion-proof housing (ATEX/Ex) for use in hazardous industrial areas.
It measures liquids non-contact over a range of 5–60 m, providing accurate and stable readings even under challenging conditions.
The sensor is ideal for tanks and process vessels in oil, gas, and chemical industries where explosion risk exists.
An integrated local display shows real-time level, temperature, and relay status. Intelligent temperature compensation ensures stable measurements across a wide temperature range, and the robust construction guarantees long-term reliability.

FAQ
1. Where can the UL30 be used?
In hazardous areas such as oil refineries, petrochemical plants, chemical facilities, and tank farms.
2. What safety standards does it meet?
The UL30 is ATEX/Ex-certified and explosion-proof.
3. How does it differ from the UL20?
The UL20 is suitable for chemical/oil tanks but is not explosion-proof. The UL30 is specifically designed for Ex-zones.
4. What liquids can it measure?
Oil, chemicals, fuels, and process liquids reliably and without contact.
5. Does it require maintenance?
No – the sensor is virtually maintenance-free due to non-contact measurement and robust Ex housing.
