Abstract:
A temperature compensated differential pressure system is provided. The system includes a pair of flanges affixed together each having a flange diaphragm therein, wherein a plurality of capillary tubes extends between the pair of flanges and a pair of opposed remote diaphragm housings. The remote diaphragm housings include a remote diaphragm therein, wherein the remote diaphragm displaces a fill fluid in pressure capillaries to displace each flange diaphragm to detect a differential pressure between each location of the remote diaphragm housings. A compensating capillary extends from the remote diaphragm housings to an opposing flange diaphragm, wherein the compensating capillary is not in operable communication with the remote diaphragms. As such, any fluctuation in fill fluid volume of the compensating capillaries due to temperature fluctuations is applied to an opposing flange diaphragm to cancel temperature effects from the differential pressure determination.
