Real-Time Fluid Identification

Non-Intrusive Fluid ID and Monitoring

These real-time fluid identification sensors have a very unique capability not found in any other sensors available on the market today. Patented by Perceptive Sensor Technologies (PST), they can identify liquids and potentially gases (future) inside a closed container, pipe, or vessel without coming in contact (non-intrusively) with the liquid or gas.  The value of this capability is high due to the reduction in installation time and costs vs other technologies which must be in contact (intrusive) with the process liquid or gas.  Products that require intrusive installation also cost downtime for installation and this is not always very easy to schedule downtime for large equipment, vessels, tanks, or pipelines when they are used for daily operations that are revenue-generating.  Secondly, this requires all components of an intrusive sensor to be chemically compatible with the process liquid or gas.  It further creates potential leak points which in turn create environmental concerns. HAWK is the Global Sales Partner for Perceptive Sensor Technologies.

Principle of Operation 

HAWK is the Global Sales Partner for Perceptive Sensors Technology (PST). PST’s patented, revolutionary non-intrusive method utilizes acoustic waves to identify the fluid content of any closed container or pipe. The technology was originally developed by the Department of Defense to identify chemical weapons inside shell casings while enforcing treaties with foreign nations. PST™ sensors have a very unique capability not found in any other sensors available on the market today.

HAWK provides sales support and offers the only non-intrusive solution resulting in real-time actionable data that is critical to operational efficiency, safety, and environmental compliance. From the Defense Sector to Petrochemicals, PST developed an underlying technology that supports applications for use in the oil and gas, petrochemical and chemical, utility, logistics, food & beverage, mining, and other industry segments.

This core technology will serve as a platform for a variety of applications including manifest verification, monitoring conditions of liquids; product movement and flow rates, inventory control, process optimization, and asset utilization across many sectors through 2025 and beyond.


The Transmix-ID™ is a clamp-on sensor capable of detecting and identifying liquid interfaces in flowing pipelines. The Transmix-ID™ technology is so revolutionary, it can decipher the difference between 87 Octane Gas and JP-8 Fuel when both liquids are flowing through a pipe. The non-intrusive unit can fit to any size pipe or container and is independently powered. The Transmix-ID™ is equipped with WiFi, Cellular or Satellite communications (or any combination thereof). The cloud-based monitoring portal identifies the liquid flowing through the pipeline and reports issues in real-time to even the most remote areas.


The Alarm-ID™ is a tank overfill and underfill protection system. This PST patented technology provides an alarm point when the identified liquid passes the sensor level either up or down. ​A series of Alarm-ID™ Units can be installed at key levels on the outside of tanks. The tank contents and even vacancy can be detected and alerts are activated in real-time 24/7.
