The present disclosure relates to a method for calculating a quality pertaining to at least one measuring tube of a Coriolis measuring device for measuring a density or a mass flow of a medium flowing through the measuring tube, wherein a determination regarding a state of the measuring tube can be made by determining various vibration properties.

A gas meter is configured for diagnostics using differential pressure (DP) measurements. The configurations include executable instructions to actively manage the DP sensor. These instructions active the DP sensor only during stable flow and, where applicable, for a defined test time period. This feature manages power consumption to maintain battery life with acceptable standards or regulations.

A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

A flow measurement apparatus can include a main flow passage, a bypass flow passage having an inlet and an outlet connected with the main flow passage, a mass flowmeter connected in the bypass flow passage between the inlet and the outlet, and a flow restrictor connected in the bypass flow passage between the inlet and the outlet. A method can include connecting the flow measurement apparatus, so that a fluid flow in the well also flows through the flow measurement apparatus, and determining at least one rheological parameter of a non-Newtonian fluid, based on an output of the flow measurement apparatus.

A method for determining a mass flow measurement is provided. The method comprises calibrating a flowmeter sensor at a first temperature and flowing a fluid having a second temperature through the flowmeter sensor. A density of the fluid is input into meter electronics. A compensated mass flow value of the fluid is determined by meter electronics, wherein the Modulus of Elasticity of the flowmeter sensor is unknown.
