Flow Switches Process Switches

A flow switch acts as a safety or control device that triggers a specific action such as starting or stopping a pump when fluid movement reaches a predetermined rate, helping to prevent equipment damage and maintain system efficiency.

Paddle switches are ideal for larger pipes and general water flow detection, whereas thermal switches provided by HK Calibrations are excellent for low-flow applications or where mechanical parts might be obstructed by debris.

Yes, our range includes intrinsically safe and explosion-proof models designed to meet strict Australian safety standards for use in oil, gas, and chemical processing facilities where flammable vapours may be present.

Calibration ensures the switch activates at the exact flow or pressure level required for your specific process; HK Calibrations provides precision-tested switches to ensure your system reacts accurately to changes in operational conditions.

While many switches are designed specifically for water or oil, HK Calibrations stocks versatile process switches that can be configured to monitor air and gas flow in ventilation systems and industrial pipelines.

Regular inspections are vital to ensure that mineral buildup or sediment hasn't obstructed the sensor or paddle; HK Calibrations recommends periodic testing to verify the electrical contact is still triggering the correct system response.
