HD500 Ultrasonic Level Meter transmitted from the sensor are reflected back from the measured object, and the distance is calculated based on the echo return time. This makes it possible to perform operations such as measuring the liquid level inside a tank, or monitoring the remaining amount of materials in a tank.

Features

Hiring high frequency ultrasonic system enables small dead zone and is possible to measure short distance.
High resolution, 0.1 mm
Minimize the main unit and sensor unit, so easy to install to the limited area.
Sensor part is chemical proof plastic (PFA).
Equipped RS-232C interface, 4-20 mA current output, Alarm output allows to communicate with existing system.
Flow measurement by measuring catchment level is possible.

Applications

Sensing or positioning goods on production line
Liquid level sensing in small size tank
