Model 633

SKU: 633

Fluid Detector, Electronic

The Delta Controls Model 633 Electronic Fluid Detector senses the pressure of a gas or liquid contained in a pipeline and if the pipeline is empty or full. Model 633 is the best option in situations where paddle-type flow switches do not provide complete or reliable detection causing spills, process shutdown, etc.

The 633 provides multiple contact closures signifying the type of fluid in the pipeline including gas, hydrocarbon, water, or a mixture. It can withstand abrasion from entrained sand in the flowing fluid. The 633 contains no moving parts, pumps, filters, columns, or valve ports.

Model 633 detects an interface as it moves down a pipeline and determines what a pipeline contains: gas, oil, water, or a mixture.
