The TLR7500 is a non-contact type continuous level meter using microwaves.
This meter determines the level of a measured object by emitting microwaves and measuring the time taken for the microwaves to travel out, be reflected and return from the object.
Since the velocity of electromagnetic waves is hardly affected by temperature and pressure, meters of this type can accurately measure levels under any conditions. Measurements are also independent of the viscosity, or changes in the density and temperature of measured objects, allowing such meters to be used for a wide range of temperatures and pressures.
Using a newly developed lens antenna, the TLR7500 can be mounted on small-diameter nozzles, and is ideal for level measurement of 80- GHz high directivity as well as ultra-small containers.
Inheriting the features of existing microwave level meters, the TLR7500 is even easier to use.
