Larger flow meter scale measurement errors caused for several reasons

Abstract: the larger the flow meter scale measurement errors caused several reasons why the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. 1. Installation does not conform to the requirements in general glass rotor flowmeter is vertical installation, the installation of the meter when the tilt Angle should not exceed 20 degrees, of course, there is also a part of the flow meter adopts horizontal installation, flow meter level, for horizontal installation. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a larger flow meter scale measurement errors caused several reasons why the article details. 1. Installation does not conform to the requirements in general glass rotor flowmeter is vertical installation, the installation of the meter when the tilt Angle should not exceed 20 degrees, of course, there is also a part of the flow meter adopts horizontal installation, for horizontal flow meter to keep level, Angle is greater than 20 degrees. Flow meter space may not be a ferromagnetic objects around 100 mm. To stay away from the valve installation position process pipeline diameter changes, pump discharge, corner, etc. Keep straight pipe before 5 d after 250 mm. 2. Large gas medium is affected by temperature and pressure meter before leaving the factory are after calibration, in accordance with the user to provide medium temperature and medium density flow calibration, the calibration gas medium under the influence of temperature and pressure is bigger, so I need the user to provide accurate temperature of commonly used. 3. Liquid medium density change larger instrument before calibration, the medium will be given according to the user density conversion, converted to calibration status of the water flow to carry on the calibration, so if the change of medium density is bigger, can cause very big error of measurement. Solution can be change after medium density into the formula of the conversion error correction coefficient, then flow meter to measure flow rate multiplied by the coefficient for the real traffic. 4: use for a long time and pipeline vibration sensing magnetic steel, a variety of factors have led float flowmeter pointer, counterweight, rotating magnetic steel parts loose, caused the error. Solution: can use first hand push pointer to verify. First of all, the position of the pointer on the RP to see if the output is 4 ma, flow display is 0%, and in turn according to the calibration for validation. If found, can be adjusted to place parts. Generally require professional personnel adjustment, otherwise it will cause the loss position, need to return to factory. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
