Flow switch for relief valve leak monitoring

Fluid Components International, headquartered out of San Marcos, California, has just released its inline FLT93L flow switch that is suitable for relief valve leak monitoring in natural gas fractionation applications. 

This product is a heavy-duty thermal dispersion flow, level, and temperature switch. It also has an all-welded thermal sensing element and advanced electronic control circuit, which is field configurable to satisfy any combination of application requirements. The thermal sensor in this switch is suitable for both gases and hydrocarbon-based liquids. The switch’s voltage output allows the user to “see” into the process and accurately set the desired trip point. The delta range between the switch’s two resistance temperature detectors provides a span for setting the switch trip points. The plant technician can set these flexible dual relays for any combination of flow, level, or temperature alarms.

The switch has a standard flow accuracy of ± 2% of the set point velocity over a ± 50°F (± 28°C) temperature range. All FLT93 series switches are temperature compensated for accuracy under rugged petrochemical plant operating conditions.
