Norriseal 1001 Liquid Level Controller 2SM60-TLDF-BA

The Norriseal Series 1001 Liquid Level Controller is a robust pneumatic device designed for precise level control in oil and gas production vessels such as separators, scrubbers, and treaters. This model, 2SM60-TLDF-BA, features a 2-inch NPT connection and is configured for left-hand mounting without a float or arm, making it suitable for applications requiring snap or throttle action for liquid level maintenance. It operates on supply pressures up to 30 PSIG and is built with durable materials like A696 body and CW displacer for corrosion resistance in harsh environments. Key benefits include reliable snap-acting or throttling control, easy field adjustments, and low maintenance due to its simple mechanical design. Advantages over similar products include its proven reliability in high-pressure oilfield settings, with a maximum working pressure of 600 PSIG and temperature rating up to 140°F, outperforming basic float switches in accuracy and durability. Drawbacks may include the need for pneumatic supply and potential weathering if not properly stored, as seen in this slightly weathered unused unit. Ideal for upstream oil and gas, chemical processing, and water treatment applications where precise level detection prevents overflows or dry runs.
