Patents Assigned to Schlumberger Industries Limited ... Abstract: A density sensor comprises a cavity arranged to receive the gas whose density is to be sensed. The cavity is divided into two chambers by a flexibly mounted diaphragm. A piezoelectric excitation device at one end of the cavity is used to excite the gas in the cavity into resonant vibration in a mode having an anti-node at the diaphragm, which causes the diaphragm to vibrate with the gas.
