APG Continuous Float Level Transmitter

This provides continuous level measurement as the sensor sends a pulse down the waveguide several times a second. Dual level measurement is also an option, where the location of two floats is determined. The electrical pulse will continue down the waveguide after hitting the first float, creating another strain pulse when it hits the second float. This is especially useful when measuring the interface between two liquids such as oil and water.

Magnetostrictive level sensors provide a high degree of repeatability, and are our most accurate liquid level measurement solution, with a resolution of about 1 mm. They are good for vaporous liquids or in heavy foam where non-contact sensors may have difficulty. Additionally, the float weight and specific gravity can be customized if the application calls for it.

Resistive level sensors comprise a float and stem, or sensing rod. The float holds a magnet, and the stem houses closely spaced reed switches and resistors. The float closes the reed switches as it travels up and down the sensing rod. Resistive is a simple, reliable, and highly repeatable way to measure liquid level. This is another form of continuous level measurement for real-time level data. Heavier floats, like on the RPM, work very well in applications where heavy build-up is present. The RPM also has the thickest stem, or sensing rod, for applications with high turbulence or flow.
