MP464SA-618-21 Flexible Mag Probe, 2-Float Capable with 1 Thermistor – (SKU: MP464SA-618-21) is a Pneumercator MP46xSA-series long-range flexible magnetostrictive level probe for bulk tank and chemical storage service, providing continuous product and interface level measurement plus single-point temperature sensing from a single tank opening.

Dual-Float Product and Interface Gauging: The MP464SA-618-21 is arranged to support two guided floats so a compatible tank gauge can read total product level and a separate water or second-liquid interface level, enabling accurate inventory control, interface tracking, and water-in-tank alarms in tall vertical tanks.

Integrated Thermistor Temperature Sensing: One built-in thermistor provides a representative product temperature signal from within the tank, allowing the monitoring system to perform temperature-compensated inventory calculations and basic product quality checks.

Extra-Long Flexible Probe for Tall Tanks: As an MP464SA model in the MP46xS Series Flexible Mag Probes range, this probe is suited to very tall aboveground bulk and chemical storage tanks, installing from the tank roof while covering the full working depth and maintaining proper top deadband and bottom clearance for both floats.

Chemically Resistant Flexible Construction: The probe uses a flexible nonmetallic sensing shaft with 316 stainless steel or compatible float and wetted components, providing corrosion resistance in petroleum products and many industrial chemicals and supporting long-term reliability in demanding bulk tank environments.

Typical Applications: MP464SA-618-21 is intended for large bulk fuel tanks, chemical storage tanks, and terminal vessels that require continuous product and interface gauging plus a single temperature point using a flexible magnetostrictive probe instead of a rigid assembly.
