Abstract
Cost effective pressure sensors for gas meters are described herein. In an example, responsive to an abnormal condition at an ultrasonic metrology unit of a gas meter, rates of pressure sensor operation are increased. In the example, the operations may include: measuring gas-environment pressure values; measuring contemporaneous air-environment pressure values; calculating pressure difference values of the gas-environment pressure values minus the contemporaneous air-environment pressure values; and comparing pressure difference values to one or more threshold values.
