Infrastructure

Infrastructure systems manage heat, flow, and materials under constant pressure, where a single sensor failure can translate to downtime, waste, or loss of quality. Precise measurement keeps heat pump installations, data centre cooling, and concrete mixing operations stable, efficient, and protected.

Solutions that worked

Heat Pumps: Flow & Temperature Measurement

Modern heat pump systems operate at low flow rates, where small measurement errors directly affect the COP and system stability. Inaccurate flow and temperature data prevent the control system from optimising performance.

  • Supplied SIKA VVX Series Vortex Flow Sensors for precise volume flow measurement from 2.5 l/min to 400 l/min across heating and hot water circuits
  • Integrated SIKA VK3/VHS06/VK309 Flow Switches for automatic pump shutdown on low-flow conditions
  • Installed SIKA WFI Temperature Sensors with Mini-Fit connector for fast measurement at evaporators, condensers, and hot water circuits
  • The control system now receives real-time, accurate flow and temperature data for optimised COP performance
  • Pump and heat exchanger protected against low-flow conditions, air bubbles, and contamination
  • Client achieved long-term, maintenance-free sensor operation with no zero-point drift across a full heating season

Data Centers: Flow Measurement for CDU & Rack Cooling Systems

High-density AI servers generate heat loads that air cooling cannot handle. Coolant flow must match server thermal loads in real time — even small imbalances cause hotspots, throttling, or shutdowns. Deionised water and glycol mixtures rule out electromagnetic flow meters.

  • Supplied SIKA VVX VA Series Vortex Flow Sensors in stainless steel for CDUs and rack-level cooling loops
  • IO-Link digital output integrates directly into BMS and DCIM platforms
  • Integrated temperature sensing delivers simultaneous flow and temperature data from a single point
  • Achieved uniform coolant distribution across all cooling loops, eliminating hotspots and preventing unplanned server shutdowns
  • Met PUE optimisation targets through precise, real-time flow control
  • Zero sensor maintenance since installation — no moving parts, no drift, no recalibration

Concrete Mixing Machines: Flow Measurement For In-Transit Concrete Management Systems

Ready-mixed concrete travels long distances by truck. To maintain slump consistency in transit, water and admixtures are dosed automatically on board. A faulty sensor renders the entire load unusable and puts the truck out of service.

  • Supplied SIKA VMZ.2 Magnetic Inductive Flow Sensor for accurate dosing of water and chemical admixtures in on-truck Concrete Management Units
  • Compact design fits within tight space constraints of truck-mounted systems
  • Chemical-resistant plastic construction handles a wide range of admixtures without degradation
  • No moving parts, operates reliably under continuous vibration, temperature variation, and chemical exposure
  • Delivered precise, logged dosing data for every load, meeting national ready-mixed concrete quality standards
  • Zero load rejections due to sensor error across thousands of trucks in daily operation
