Abstract: the maintenance of orifice meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. We use the orifice meter must learn to understand and maintenance, otherwise it is a good meter also of no help, let's take a look at cycle check meter. 1, automatic adjustment or phases, namely when the orifice flowmeter test according to routine, if by mistake. More flow meter manufacturers choose model price quote you are welcome to inquire, here is late orifice meter scale of maintain article details. We use the orifice meter must learn to understand and maintenance, otherwise it is a good meter also of no help, let's take a look at cycle check meter. 1, automatic adjustment or phases, namely when the orifice flowmeter test according to routine, if error within the scope of the permit, should extend the next test cycle, such as beyond permissible error, should shorten the test period. 2, the using time, the equipment connected to the meter, when the actual working hours meter accumulative total of flowmeter e. , reaching the orifice meter verification, according to the above method to determine the cycle. 3, online test or & other; Black & throughout; Test method, which USES a portable standard device frequently online detection limit parameters or use special & other; Black & throughout; Check the selected parameters, if it is found that flow meter is unqualified, the flowmeter should be a comprehensive check, this is a kind of cycle after verification. 4, schedule time method, the batch accuracy level of the same orifice meter, according to the conditions of use are grouped, each test cycle, and preliminary decision for each set of flowmeter, within the prescribed period, if the proportion of unqualified orifice meter is too high, should shorten the test period, if the unqualified ratio is very low, can prolong the verification period. 5, control chart method, choose the same calibration points from each calibration, the calibration results by time tracing point, according to the dispersion and drift is calculated. 6, reliability analysis method, this method can be found in the national metrological verification procedures JJG1024 - 91 the principle of reliability analysis for the measuring instruments. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
