Displacer

2 products

Displacer Level Instruments determine liquid levels by measuring the buoyant force on a submerged weight (displacer). Known for robustness, they excel in heavy-duty environments—such as wastewater, oil, or chemical processing. The mechanical simplicity makes them easy to install and maintain, while their accurate output supports level control and alarm systems. For applications requiring solid performance and minimal maintenance, displacer units offer time-tested reliability and precision.

Frequently Asked Questions

These instruments operate based on Archimedes' Principle, measuring the buoyant force exerted on a submerged weight called a displacer. As the liquid level in a tank rises or falls, the apparent weight of the displacer changes. This change is mechanically or electronically translated into a precise level reading, supporting critical control and alarm systems.

HK Calibrations currently features two primary configurations for industrial use. The Series 190 is a single-stage top mount unit designed for standard level monitoring. The Series 195 is a two-stage top mount unit, which provides the added capability of managing two separate switching points for complex pump or alarm sequences.

Because of their robust design and mechanical simplicity, displacers are the go-to choice for heavy-duty applications. They are highly effective in wastewater treatment, chemical processing, and oil and gas industries, where reliability in harsh environments is a top priority.

The top-mount configuration of the Series 190 and 195 allows for easy installation via the top nozzle or flange of a vessel. This setup is particularly advantageous for maintenance, as it allows for the inspection of the control mechanism without the need to drain the tank or disrupt the stored liquid.
