Specialty Engineering Tools / Equipment

Evidence, not guesswork — high-resolution measurements that reveal what’s really happening inside building water and drainage systems.

H2WISE has specialised tools for fault finding, commissioning, and gathering real-world data — helping consultants, builders, plumbers, developers, and facility managers understand what’s really happening inside their systems. Through our technology partners, we can extend this capability into whole-of-life data gathering and rules-based control systems, allowing clients to continuously monitor performance, identify anomalies early, and make data-driven maintenance decisions.

With data comes knowledge — and with knowledge, design becomes informed, safer, and smarter. Replacing a failed component without understanding why it failed is doing the same thing again and expecting a different result. We use specialised diagnostic equipment and sensors to capture pressure spikes, flow dynamics, water quality, and transient events invisible to the naked eye.

In engineering, data is more than numbers — it’s understanding. When measured and interpreted correctly, it transforms unknowns into insight. Research by Josey et al. (2021) showed that water demand predictions in AS/NZS 3500.1 can overestimate actual flows by 217–326%, leading to systemic oversizing and inefficiency (read the paper). Meanwhile, Gormley et al. (2025) demonstrated that sanitary pressure transients can generate aerosols capable of transporting pathogens through building drainage systems (read the paper). Together, these studies highlight a simple truth: without measurement, design assumptions are blind.

Ultrasonic clamp-on flow meter

Ultrasonic Flow Meter (Clamp-on)

Non-disruptive • Potable/RO/softened/chilled

Two-channel clamp-on meter for engineering-grade flow/velocity logging. Quantifies true demand profiles, leakage, and spare capacity to avoid oversizing and verify system utilisation.

Use cases: demand truthing, capacity checks, leakage detection, water-age assessment from diurnal profiles.

Sewer flow meter/logger

Sewer Flow Meter / Logger

Non-disruptive • In-pipe velocity/level

Low-rag sensor records sewer flow and level over time. Supports precinct planning and infiltration studies; can pair with rainfall logging to correlate events.

Use cases: inflow/infiltration, stormwater ingress, capacity validation for upgrades.

Sanitary stack air pressure transient logger

Sanitary Air Pressure Transient Logger

Non-disruptive • Stack air-side pressures

High-frequency capture of positive/negative air transients that threaten water trap-seal integrity and can drive aerosol migration. Supports PCA performance verification in healthcare.

Use cases: trap stability checks, fault tracing (venting/roof effects), risk reviews for occupied healthcare spaces.

Water pressure transient loggers

Water Pressure Transient Loggers

Cut-in at valve • H&C services

Captures spikes and cyclic stresses in potable hot & cold services. Spectral analysis helps locate sources such as PRVs, pumps, quick-closing fixtures, or resonance.

Use cases: nuisance failure diagnosis, cavitation/resonance, commissioning acceptance.

Water chemistry test kit

Water Chemistry Photometer & Field Meters

On-site analysis • Hygiene & corrosion indicators

Rapid field chemistry for the most diagnostic metrics (e.g., free/total chlorine, hardness, alkalinity, chloride, iron/copper, pH/EC/DO/turbidity/ammonia). Links chemistry to hygiene/corrosion risk for actionable decisions.

Use cases: disinfectant performance, corrosion risk screening, commissioning baselines.

Total bacterial activity sampler

Total Bacterial Activity (ALP) Sampler

Rapid assay • VBNC-inclusive activity

Biochemical field method measuring living microbial activity via alkaline phosphatase—ideal for hotspot screening where culture methods miss VBNC organisms.

Use cases: risk mapping, pre/post-intervention validation, domestic hot-water hygiene checks.

Thermal imaging camera

Thermal Camera

Visual thermal patterning • Non-intrusive

Reveals thermal imbalance in headers and return loops; highlights cold legs, trapped air indications, and short-circuiting that reduce DHW performance.

Use cases: equal-flow header verification, circulation troubleshooting, QA at commissioning.

Temperature data loggers

Temperature Logger Packs

Multi-point • Continuous logging

Distributed sensors track supply/return and branch temperatures over time to confirm set-points, detect cross-flow, and prove circulation performance.

Use cases: TMV verification, recirc balancing, seasonal optimisation.

Ultrasonic thickness gauge

Ultrasonic Thickness Gauge

Non-destructive • Wall-loss screening

Assesses erosion-corrosion and remaining wall thickness in copper and other services without cutting. Best interpreted alongside chemistry and failure history.

Use cases: localised wall-loss mapping, replacement scoping, lifecycle planning.

Hot-wire anemometer

Hot-Wire Anemometer

Vent measurements • Diagnostic

Measures airflow within sanitary vents to understand wind/stack effects on odour and trap stability where venting is marginal or roof interaction is suspected.

Use cases: vent performance studies, stack behaviour characterisation.

Phase-contrast microscope

Phase-Contrast Microscope

Sample-based • Forensic support

Forensic inspection of corrosion samples and failure fragments to correlate material state with operating history and site chemistry.

Use cases: failure mode ID, evidentiary documentation with photomicrographs.

Field diagnostic toolkit

Other Handy Tools

Field kit • Rapid diagnostics

Temperature probes, micrometers, fixture flow cup, and custom diagnostic cases that make live-system triage and commissioning efficient.

Use cases: quick triage, evidence packs, commissioning aids.
