DEVICE FOR COMPENSATION OF ERROR OF MEASUREMENT OF ULTRASONIC LOCATOR Russian patent published in 2016 - IPC G01N29/36 

FIELD: measuring equipment.

SUBSTANCE: invention can be used for compensation of ultrasonic locator error of measurement. This invention consists in fact that device for ultrasonic locator measurement error compensation comprises two independent channels, each of which comprises generator of ultrasonic signals, connected to emitter and series-connected receiver, amplifier, threshold device, time interval generation unit, unit for measuring time interval. To first and second threshold devices reference voltage source is connected, and to first and second time interval measurement units quartz generator is connected. Third time interval measurement unit is connected to first threshold device, to quartz generator and control unit, which is connected to first and second generators, with first and second time interval generation units, with first and second time interval measurement units and indication unit.

EFFECT: technical result is reduced measurement error.
