CORRECTION SYSTEM OF FRACTIONAL VALUES OF THE CONSTANT OF CONVERSION OF FLOW SENSING ELEMENTS

摘要

System for correcting flow sensor conversion constant fraction values, containing flow sensor with impulse signal connected to formatting circuit input, divider of integer values, integrator, initial zeroing circuit, RS trigger, generator of auxiliary impulses, differentiating circuit and LUB gate; is characterised in that input of formatting circuit (2) connected to the sensor (1) is attached to one of the RS trigger inputs (3), which has its output connected with input triggering auxiliary impulses generator (4); the latter having its output connected with the input of integer values divider (5) and with the meter input (7); whereas the meter input is connected through the differentiating circuit (8) to one of the inputs of the LUB gate (9), and its second gate is connected with the initial zeroing circuit (10), which also connected to the second input of integer values divider (5), whose input controls the integrator (6), while an output of the LUB gate (9) is connected with the second input of the trigger RS (3) and with the zeroing input of the meter (7).IMAGE
