Flowmeter

How it is used

Used for control, mass balances and custody transfer (buying and selling by quantity). Engineers choose the type based on fluid, accuracy and cost, and check straight-pipe requirements. Coriolis meters measure mass flow directly.

Example sentences

1. The magnetic flowmeter won't work on this solvent because it doesn't conduct electricity.

2. The two flowmeters disagree by 6%, so one of them needs to be checked.

Related terms

• flow rateThe amount of fluid that passes a point in a given time, given either as mass (kg/h) or as volume (m³/h).
• transmitterA field instrument that measures a value such as pressure, temperature, level or flow and sends it as an electrical signal, often 4–20 mA, to the control system.
• control loopA set of parts that work together to hold one process variable at its setpoint: a sensor and transmitter, a controller and a final element such as a control valve.
• mass balanceA calculation based on the rule that mass is not created or destroyed: everything that goes into a system must come out, react or build up inside it.
