ULTRASONIC LOCATOR MEASUREMENT ERROR COMPENSATION DEVICE Russian patent published in 2021 - IPC G01F23/296 

FIELD: measurement equipment.

SUBSTANCE: invention relates to ultrasonic location meters for the level of liquid and bulk products. The ultrasonic locator measurement error compensation device contains an ultrasonic pulse generator connected to an emitter, a receiver connected to an amplifier, to the output of which two threshold devices with different threshold voltages are connected, two reference voltage sources connected to the inputs of the corresponding threshold devices, the outputs of the threshold devices are connected to the corresponding time interval generation units, the outputs of which are connected to the control and display unit, the outputs of which are connected to the input of the generator and to the input of the first time interval generation unit. As reference voltage sources, adjustable reference voltage sources with variable voltage are used, the inputs of which are connected to the outputs of the corresponding regulators, the inputs of which are connected to the control and display unit. In this case, the output of the first time interval generation unit is connected to the second input of the second time interval generation unit.

EFFECT: reduction of measurement errors.
