Tank Level Indication

Tank Level Indicators






Monitoring tank levels continuously and remotely using hydrostatic pressure represents one of the most proven and reliable methods you can employ. Well suited to a variety of applications, pressure transmitters can provide simple and accurate means for measuring liquid level in storage or processing tanks.

Inventory Monitor/Process Control

Inventory Management - Process Control







Inventory tank gauging (as opposed to simple level measurement) affords a higher degree of accuracy and consistency for reporting. Here the flexibility to monitor both volume and weight of material satisfies the needs of processing and accounting. Our product offerings simplify the task of integrating data throughout your operation via network interface to PLCs, HMIs, and enterprise systems.

Hazard/Explosion Zone

hazardous Materials/Explosion Zones






It can be challenging and costly to install equipment in hazardous/explosion zone environments. Fortunately, there are effective solutions that employ inherently safe pneumatic components within these critical areas. We offer proven, reliable liquid level tank sensors that do no require electronic components at the tank and transmit a pneumatic output signal.

Ballast Monitoring

Ballast Monitoring






A critical application for most vessels and semi-submersible drill rigs is ballast water monitoring. Our LiquiSeal and Purge Control bubbler systems are a proven technology for marine tank gauging for both ballast and draft measurement. Our hydrostatic pressure measurement simply requires a length of pipe extending downward within the tank — no internal components whose periodic recalibration or failure could necessitate personnel entering the tank (or compartment).
