The OUL series ultrasonic level transmitter uses high-frequency sound waves to measure liquid or solid levels. The transmitter emits pulses, which reflect off the surface, and the time taken for the reflection to return is calculated to determine the level. It offers high accuracy, non-contact measurement, and reliable performance.
The OUL series ultrasonic level transmitter is a standard remote ultrasonic level transmitter for continuous non-contact level measurement in liquids and solids. It consists of probe and host, both of which are plastic leak-proof structure. The series can be widely applied to the metallurgical, chemical, electricity and oil industries.
Integrated design installed conveniently.
Protected in the excessive voltage and current
Protected in the thunder and lightning.
The big window of LCD is easy to debug and read.
Over-voltage over-current protection, lightning protection.
Advanced terminal design, to ensure that wiring never loose.
Intellectual signal treatment technology, guarantee that the instrument meets various kinds of harsh operating occasion.
All plastic probe, acid and alkali resistant, adapt to bad environment;
The OUL series ultrasonic level transmitter is widely used in industries such as portable water, heat supply, water management, metallurgy, chemical processing, and energy.
The level transmitter can be installed for process management, temporary checking, it is essential to the monitoring systems.
