Rototherm’s quality differential pressure gauges are designed to measure the difference in
pressure between two points in a system and show it on a single dial gauge. A magnetic
movement senses the differential pressure. The gauge has separate pressure and indicating
chambers.
These diaphragm instruments can indicate small values of differential pressure even when
used at high line pressures. They provide instantaneous and continuous information regarding system conditions helping in eliminating premature servicing of equipment, avoid unscheduled down time of costly processes and can detect abnormal system conditions.
