Correct meter scale error method

by:Sincerity     2021-01-29
Abstract: the method of error correction meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Flowmeter measurement minus the difference obtained by measuring the true value of known as measurement error, error for short. When the instrument error occurs can adopt the following methods for correction. 1, flowmeter flow coefficient correction a, big flow test in zui, standard is given. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the article details correct meter scale error method. Flowmeter measurement minus the difference obtained by measuring the true value of known as measurement error, error for short. When the instrument error occurs can adopt the following methods for correction. 1, flowmeter flow coefficient correction a, big flow test in zui, are given in the standard of standard values for Q standard; B, at the same time by check meter readings for Q meter; C, press K readout instrument current flow parameters C1 ( Old) ; D, according to the formula of C1 ( New) =C1( Old) × Q/Q meter, calculate the new flow coefficient C1; E, and then put the new flow coefficient instead of the original flow coefficient C1 ( Old) 。 2, current transmitting coefficient correction a. Zero flow transmitting current is 4 ma fixed: & other; 10' ( New) =“ 10' ( Old) × 4 ma/A0 formula: & other; 10' ( New) : the new four ma current transmitting coefficient; “ 10' ( Old) : read the meter coefficient of the current mail 4 ma; A0: zero flow transmitting current measured values ( mA) 。 b。 Current mail full scale factor correction: & other; 11. ' ( New) =“ 11. ' ( Old) × 16mA/( A01 - 4mA) Formula: & other; 11. ' ( New) : the new mail full scale coefficient; “ 11. ' ( Old) : read the letters full scale coefficient; A01: full scale flow when transmitting current measured values ( mA) 。 Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
