01
APPLICATION
Custody-transfer flow metering
Money changes hands on the measurement, so uncertainty and traceability must be demonstrable.
02
RECOMMENDED APPROACH
How it is solved
A Coriolis meter measures mass flow directly, so pressure and temperature changes do not distort the reading. Redundant ultrasonic clamp-on meters provide a verification path without opening the line.
RECOMMENDED PRINCIPLE
Coriolis mass flow
Oscillating tubes twist in proportion to mass flow; phase shift between sensors gives direct mass flow, density and temperature.
How it works →
RECOMMENDED PRINCIPLE
Transit-time ultrasonic flow
Ultrasonic pulses travel faster with the flow than against it; the time difference gives velocity.

TYPICAL LOOP
How the measurement fits the process
Instruments sit on the equipment they protect, send their signal to the controller and act through the final element. Demonstration drawing, not a design.
