28For the selection of the flow rate units and the number of decimals it must be taken intoaccount that an indication with an excess of decimals may give the sensation of instability ofthe reading. As a general rule it can be considered that the reading should not have morethan a total of 5 digits (integer + decimals).7.4 Flow rateThis screen displays a submenu to modify different aspects related to flow reading, such ascut off, reversal flow, filtering and offset.7.4.1 Cut offA cut off flow rate can be programmed, that means, the flow rate below which the flow rateindication will be zero. This can avoid reading errors in the lower zone of the scale.7.4.2 Reversal flow rateThe MBC1 is a bi-directional converter. The flow rate changes its sign automatically whenthe flow is reversed. If after the converter has been installed it is necessary to reverse theflow rate sign, in this screen it can be done by selecting the option REVERSAL– Yes.NOTE: The totalizer increases only when the flow rate is positive.7.4.3 DampingThe MBC1 converter has an adaptive filter (damping) to provide stable flow rate and analogoutput readings in the presence of continuous flow rate fluctuations.
