How does an electromagnetic flow meter work?

• Measures conductive liquid flow using voltage generated in a magnetic field. Works only with conductive liquids (water with ions, etc.).

• Measures flow by detecting changes in pressure across a constriction. Can be used with any liquid or gas.

• Uses ultrasonic waves to measure the velocity of any fluid, regardless of conductivity.

• Measures flow by counting mechanical rotations of a turbine in the fluid stream.

Differential Pressure Cell (Level)

How does it work?

• Measures the pressure difference between the top and bottom of a tank to calculate the liquid level. The specific gravity or density of the liquid is used in the calculation.

• Measures the temperature difference between the top and bottom of a tank to calculate the liquid level.

• Uses ultrasonic waves to directly measure the height of the liquid in the tank.

• Calculates the liquid level based on the color of the liquid detected by a sensor.

Float & Displacer Level Devices

How do they work?

• Float type: rides the liquid surface; movement is linked to a mechanism or transmitter to indicate level. Displacer type: suspended in liquid; movement is linked to a mechanism or transmitter to indicate level.

• Float type: measures temperature changes; Displacer type: measures pressure changes.

• Float type: uses electrical conductivity; Displacer type: uses magnetic fields.

• Float type: detects color changes; Displacer type: detects sound waves.
