CUSTOM TANK LEVEL ALARMS for our customers for challenging needs.
CUSTOM TANK LEVEL ALARMS
We make custom tank level alarms of all types. If its liquid, we can sense it and produce an alarm if it gets high or low, or both. Viscous liquid, coating liquids, extremely corrosive, we have seen it before.
Float switches handle 99% of all level sensing applications. They are extremely reliable, chemically resistant, low cost, versatile, relatively small size, and consume no power. Float switches should always be considered first for a level sensing project. But what if the liquid coats the float switch and stem, then here is a discussion of other options.
Hybrid materials BUNA+PVDF
For high temperature oils this makes sense to use a BUNA float switch which is rated for 250ºF. BUNA is very compatible with hydrocarbons and has a low specific gravity of just 0.5. Mounting this float switch in a PVDF pipe and float mount which are rated to 300ºF, provides a tank alarm for service in very hot tanks.

Weighted Level Probe…
For very deep tanks where a conventional pipe wold be too long, we constructed this level probe which is dangled in the solution. The probe is weighted to keep it down and to keep the cable taut. The cable is PVDF coated to resist the tank chemicals.
Low Profile Tank Alarm…
This is for an automatic plating line that must not interfere with a hoist traveling over the rim of the tank. Total height only 2 inches. Float depth extends from 2-4 inches into the tank. The sliding pipe is sealed with a rubber gland. We have even lower profile options too like our level probes but this is an all-in-one unit solution.
