Chemical Loading

Chemical Static Grounding, Overfill Prevention and Identification Systems

Since 1935, Scully has been setting standards in tank filling safety. Our systems provide static grounding protection, prevent spills, and offer vehicle identification to ensure safe loading in everything from tank trailers/road tankers to rail cars and storage tanks.

What sets Scully systems apart? Our electronic overfill prevention systems automatically check the system status and their own internal circuitry 30 times per second for the ultimate in safety. No other system offers this level of safety. Scully systems are also known for their reliability. Scully spill prevention systems have been operating in chemical and petroleum applications for over 50 years and are unmatched in their safety record.

Flexim Ultrosonic flow - Chemical Industry

FLUXUS® measures flow rates non-intrusively with ultrasound. Clamp-on ultrasonic transducers are simply mounted on the outside of the pipe. The practical advantages are obvious: no wear and tear by the medium flowing inside the pipe, no risk of liquid leakage or fugitive gas emissions, no pressure loss and, above all, unlimited plant availability.

Mechanical Level Gauge

Float and Tape Gauges Simple, Safe and Reliable Inventory-Grade Level Measurement Float and tape gauges, also known as “automatic tank gauges”, have been in the marketplace for over 90 years. This tried and true method works by using a large float inside the tank attached to a negator spring via a perforated tape. The negator spring provides constant tension, which balances the float on the liquid. The liquid level in the tank is displayed on the gauge counter or indicated on the gauge board.
