Pressure type level meter
MPL series
- Pressure type level meters
allow a wide range of measurements with high precision -
Outputs the liquid level continuously by measuring the liquid pressure near the bottom of the tank. Simple zero and span adjustment by pressing one touch pushbuttons.
Compact design with the amplifier integrated into the case makes for easy installation.
It has both delay setting and abnormality notification function.

Features, keys
- The pressure receiver is a double diaphragm type
The liquid contact parts are made of highly corrosion-resistant SUS316L. Therefore, the meter is very durable and corrosion resistant. - Wide measuring range and high precision
This meter achieves higher precision than ordinary models; 30kPa (at a water depth of 3m), and a linearity of +-0.5%. - Simple to adjust
It is easy to make the initial adjustments and span adjustment, using pushbuttons.
You can adjust the response speed using the delay setting function. - A wide range of power supply can be used
Since these units can handle a wide range of power supply specifications (20 to 250 VAC/DC), they can be used in any location in the world.

* The video demonstrates actual measurement using this sensor.Usages, use examples
- Liquids whose specific gravity does not change
- When the meter cannot be install on the top of a tank.
