HVAC

Instrumentation used in the HVAC industry

Premier Control Technologies have many instruments to compliment the HVAC industry, should this be measurement of flow, temperature, humidity or pressure.

Heating, Ventilation, and Air Conditioning (HVAC) systems in the UK and Ireland must comply with strict energy efficiency and indoor air quality standards set by CIBSE, BSRIA, and EN 16798. Accurate flow, pressure, temperature, and humidity control are essential for commissioning, balancing, and maintaining system performance.

This page highlights key HVAC applications and the technologies that help achieve compliance, optimise energy use, and ensure reliable operation.

Typical applications

Chilled water flow monitoring

Chilled water circuits are critical for cooling in HVAC systems. Accurate flow measurement ensures energy efficiency, proper heat exchange, and system balance. Non-invasive solutions allow retrofit without downtime, making them ideal for existing installations and energy audits.

Relevant products:

  • Dynasonics TFX-5000 Clamp-On Ultrasonic Flow Meter - This meter provides non-intrusive flow measurement for chilled water systems. It clamps onto the outside of the pipe, eliminating the need for cutting or shutdown. It supports bidirectional measurement and energy calculation when paired with temperature sensors.
    Key benefits:
    • Clamp-on installation (no pipe cutting)
    • Bidirectional flow measurement
    • Energy calculation capability
    • Wide pipe size compatibility
