LIQUID-LEVEL METERS
POLYUS Research
& Development Institute
offers a UDL type Laser Liquid Level Indicators for non-contact
measurement of linear displacement, distance (level) to liquid and
various materials with low reflectance. The indicators operate in
automated technological process, they have duct and moisture protective
package and can operate in aggressive environment.
