A system for detecting tampering in a signal conditioner of electronics that determines a parameter from signals received from one or more sensors is provided. The system includes a host system that receives the parameter signals from the signal conditioner indicating properties of a material and supplies power to the signal conditioner. The signal conditioner is remote from and coupled to said host system. The signal conditioner generates the parameter signals. The host system is configured to periodically transmit a request for said authentication information to said signal conditioner, receive said authentication information from said signal conditioner in response to said request, compare said authentication information with initial authentication information, and detect said tampering condition in said signal conditioner if said authentication information is not equal to said initial authentication information.

System for preventing tampering with a signal conditioner remote from a host system

A system, method, and software are disclosed that determine a proportion of a majority component of a fluid that is flowing through a Coriolis flowmeter. Circuitry receives pickoff signals and a temperature signal from the Coriolis flowmeter responsive to the fluid being flowed through the Coriolis flowmeter. The circuitry processes the pickoff signals and the temperature signal to determine a proportion of the majority component relative to the fluid. To determine the proportion of the majority component in one example, the circuitry determines a first volumetric flow rate based on a measured mass flow rate of the fluid and a reference density of the majority component. The circuitry then determines a second volumetric flow rate based on a measured volumetric flow rate, a temperature-varying density, and the reference density. The circuitry determines the proportion of the majority component based on the first volumetric flow rate and the second volumetric flow rate. The circuitry can advantageously determine the purity of the fluid to more accurately measure volumetric flow rates.

Majority component proportion determination of a fluid using a coriolis flowmeter

The fluid delivery system comprises a Coriolis mass flowmeter, a pump, a recirculation valve, and/or a back-pressure valve. The fluid delivery system prevents the measurement of a multiphase fluid flow without the need for an air eliminator and strainer. The Coriolis mass flowmeter measures the density value of the fluid product being delivered from a fluid source to a destination. The Coriolis mass flowmeter compares the measured density value to at least one of an upper threshold density value and a lower threshold density value. If the measured density value exceeds the at least one of the upper density value or the lower density value, the flowmeter automatically shuts down the pump and closes the back-pressure valve to stop the delivery of the fluid product from the fluid source to the destination to prevent the measurement of a multiphase fluid flow.
