Five product families purpose-built for data center liquid cooling. Whether you're commissioning a hyperscale CDU farm or retrofitting a colocation hall with rear-door heat exchangers, we cover flow, temperature, pressure, level, and water chemistry from a single vendor.
Precision flow measurement for primary/secondary CDU loops, immersion tanks, and direct-to-chip manifolds. Compatible with water, glycol-water, and dielectric fluids.
| Accuracy | ±0.2% of reading |
| Size range | DN15 – DN400 |
| Output | 4–20 mA, Modbus RTU, HART |
Fast-response RTDs and thermocouple assemblies with integrated 4–20 mA transmitters for supply/return loop, cold plate inlet/outlet, and rack-level monitoring.
| Accuracy | Class A / Class AA RTD |
| Range | −50°C to +200°C (liquid cooling band) |
| Output | 4–20 mA HART, Modbus, direct RTD |
Silicon piezoresistive transmitters engineered for low-pulsation cooling loops. Gauge and differential variants for filter monitoring, pump ΔP, and manifold balancing.
| Accuracy | ±0.075% of span |
| Range | 0–100 kPa to 0–25 MPa |
| Output | 4–20 mA HART, Modbus RTU |
Non-contact and guided wave level sensors for coolant reservoirs, expansion tanks, and immersion dielectric baths. Unaffected by vapor, foam, or condensate on tank walls.
| Accuracy | ±3 mm (guided wave) |
| Range | 0.1 – 20 m |
| Output | 4–20 mA, Modbus, relay |
Online analyzers that detect corrosion precursors, biofilm risk, and coolant chemistry drift before they impact hardware reliability. Integrates with BMS/DCIM via Modbus.
| Parameters | pH, EC, DO, ORP, turbidity |
| Accuracy | pH ±0.02, EC ±1% FS |
| Output | 4–20 mA, Modbus RTU, dual relay |
A quick map from cooling architecture to the typical instrumentation package. For detailed selection criteria, see the architecture-specific guides on our Solutions page.
Cold-plate cooling for GPUs and CPUs. Tight inlet temperature control and differential pressure monitoring are critical.
Servers submerged in dielectric fluid. Level, temperature distribution, and dielectric purity are the core measurements.
Water-cooled doors on standard air-cooled racks. The simplest liquid retrofit, but still needs per-door metering for billing and diagnostics.
The heart of any liquid-cooled hall. Primary (facility) and secondary (IT) loops need full instrumentation including chemistry.
Every Supmea instrument ships with the industrial protocols your building management and data center infrastructure management platforms already speak. No custom drivers, no middleware.
| Product | Accuracy | Protocol |
