When sizing a regulator, always use the lowest inlet pressure, the highest outlet pressure, and the maximum capacity desired. Type 61HP Pilot Type 61H Pilot isher Tips 25. When installing a working monitor station, get as much volume between the two regulators as possible. This will give the upstream regulator more room to control intermediate pressure. - 61
