Non-Invasive level switch
High/Low Position alarm
Alarm position – At any place required. Not limited by fixed hole on the side wall.
Non-contact with the liquid inside.
No maintenance, not influenced by (exp: thick oil deposits).
No tank break in; Non-side drilling; No flange
No shutdown/empty tank during installation.
Local Alarm & Display/Relay output to PLC
The Non-Invasive level switch is a new type of liquid level monitoring and alarming device. It is mainly used to monitor the liquid level of the storage tank, realize the upper and lower limit alarm or monitor whether there is a medium in the pipeline (dry state protection). It can be applied to the liquid level process control of medicine, petroleum, chemical industry, power, food, and other industries.
The sonar pulse generated by the sensor (probe) of the Non-Invasive level switch can pass through the container wall. This pulse will propagate in the container wall and liquid and will be reflected back. Through the detection and calculation of this reflection characteristic, it can be judged whether there is liquid in the container at the monitoring point. the level switch can output relay signals to PLC, SIS, etc, so as to realize the monitoring or control of liquid level on the system.
