Factory Price RS485 4-20mA Non Contact Water Tank Fuel Oil Ultrasonic Liquid Level Sensor

Product Description

The meter includes several proprietary technologies, is safe and clean, with high precision
and long service life, stable and reliable, and convenient to install and maintain, and is
applicable to various fields of acid, alkali, salt, anticorrosion, and high temperature.
The meter is with following features:

For circuit design, high-quality power modules are selected to be as power supply parts
and highly stable and reliably imported devices are used as components of the meter. It
can fully replace imported foreign meters of the same type.

Patent sonic-wave intelligent technology software can make intelligentized echo analysis.
It needs neither debugging nor other special steps. This technology has functions of
dynamic thinking and dynamic analysis.

Our sonic-wave intelligent patent technology greatly improves the meter's precision, and
the precision of liquid level is up to 0.3%, which is enough to resist various interference
waves.

The meter is a non-contact one and does not directly contact liquid, so the fault rate is low.
The meter can be installed in several different ways, and the user can make meter
calibration according to the Manual.

The meter's all input and output lines must be with such protection functions as lightning
protection and short circuit prevention.
