Case Study 1: Smart Compressed Air Monitoring System – Speciality Steel Plant

Client: A Speciality Steel Manufacturing Plant in Tamil Nadu operating 3 Centrifugal Compressors with a total capacity of 14,700 CFM, consuming approximately 75,000 kWH per day.

Challenge: The plant faced multiple issues including inaccurate flow measurements from orifice plate sensors causing 0.2 bar pressure drops, misleading dew point readings from refrigerant dryers (actual PDP was 20°C instead of displayed 3-7°C), vortex flow sensors causing pressure fluctuations at production headers, leakages of up to 750 CFM, and artificially high compressor loading pressures set 1 bar above requirement.

Solution: WiseAir 4.0 Smart Monitoring System was deployed in 4 steps — replaced 3 orifice plate sensors with WAFS-103 Pitot Tube Flow Sensors (zero pressure drop), installed WADS-205 Pressure Dew Point Sensors with buzzer alarms, replaced all 21 vortex flow sensors with WAFS-106 Thermal Mass Flow Sensors, and digitalised the entire system with AI-powered WASM-601 Real-Time Monitoring Software.

Results:

• Saved 1,104 kWH/day by eliminating orifice plate pressure drops (ROI: 83 days)
• Reduced leak reoccurrence by 60%, saving 500 CFM or 1,718 kWH/day (ROI: 27 days)
• Lowered compressor loading by 0.5 bar, saving 1,862 kWH/day (ROI: 9 months)
• Investment of Rs 75 Lacs resulted in savings of over Rs 2.32 Crores in energy costs
• Overall project ROI achieved in just under 4 months
• Stable system pressure, improved air quality, and reduced maintenance costs

Case Study 2: Reducing Energy Losses by Replacing Orifice Plate Flow Measurement

Client: A leading process manufacturing facility operating a large compressed air distribution network for energy monitoring and internal audit compliance.

Challenge: The plant was using a conventional orifice plate flow meter that created permanent pressure drops across the measurement point. This forced compressors to work harder, increased energy consumption, provided limited accuracy during low-load conditions, and made it impossible to quantify idle-air losses effectively.

Solution: The orifice plate was replaced with the WiseAir WAFS-103 Differential Pressure Pitot Tube Flow Meter — an insertion-type design that eliminates permanent pressure drop. Installation required only a ½-inch hole through a standard ball valve with no pipe cutting, welding, or production shutdown.

Results:

• Complete elimination of measurement-induced pressure drop
• Stable, repeatable flow readings across varying load conditions
• Improved low-flow accuracy and reduced compressor load
• ROI achieved in less than 6 months
• Continuous reduction in power consumption with lower maintenance costs
• IIoT-ready integration with centralized dashboards and energy-management platforms

Case Study 3: Turning Compressed Air from Cost Center to Controlled Asset

Client: A leading textile manufacturing facility with compressed air powering looms, pneumatic controls, and cleaning systems across the production floor.

Challenge: The plant had zero measurement of actual compressed air consumption, no visibility into which production sections were drawing excess air, suspected but unquantifiable leakages, pressure instability causing inconsistent equipment performance, and compressors running on fixed schedules rather than actual demand.

Solution: WiseAir deployed a comprehensive measurement infrastructure across 8 critical distribution lines — 11 x WAFS-104 Thermal Mass Flow Sensors and 11 x WAPS-501 Pressure Sensors (22 sensors total). All sensors were installed online without any production shutdown.

Results:

• Hidden compressed air leakages identified and located using flow anomaly data
• Pressure drops pinpointed to specific line segments for targeted repairs
• Compressor operating setpoints corrected based on real demand data
• Over-pressurization reduced, cutting unnecessary compressor load
• Section-level consumption benchmarks established for ongoing tracking
• Estimated energy saving potential of 8–15% identified through data analysis

Case Study 4: Precision Water Flow Measurement for a Textile Dyeing Plant

Client: A textile dyeing plant requiring precise water flow control for consistent dye-to-water ratios and colour quality across production batches.

Challenge: The existing flow sensor had degraded over years of operation, resulting in inconsistent flow readings, joint leakage, rust formation, manual intervention to regulate water input, and colour variation across batches. Even minor deviations in water volume led to shade variation, reprocessing, fabric rejection, and increased chemical and water waste.

Solution: WiseAir replaced the failing sensor with the WUFS-905 Electromagnetic Flow Meter — designed specifically for conductive and chemically aggressive liquids. It features ±0.5% accuracy, no moving parts (zero leakage, zero corrosion), bi-directional flow measurement, and pulse output for seamless PLC integration enabling fully automated water dosing.

Results:

• Accurate flow measurement batch after batch
• Consistent dye ratio control with colour consistency restored
• Zero joint leakage and no corrosion-related reliability issues
• Fully automated water dosing via PLC integration
• Real-time flow visibility enabling data-driven process control
• Minimal production disruption during installation

Case Study 5: Life-Critical Medical Oxygen Flow Monitoring for a Hospital Network

Client: A multi-location hospital network with centralized oxygen generation and distribution systems supporting ICUs, operation theatres, and emergency wards.

Challenge: Medical oxygen delivery systems demand continuous flow monitoring without interruption, immediate detection of supply variations, accurate low-flow measurement for patient safety, zero tolerance for errors, and 24/7 operational reliability. The hospital required a high-precision, maintenance-free solution compliant with healthcare infrastructure standards.

Solution: WiseAir deployed WAFS-105 Inline Thermal Mass Flow Sensors at critical oxygen pipeline locations across multiple hospital branches. The sensors feature an ultra-wide 1:2500 turndown ratio, no-moving-parts design for long-term reliability, vibration-proof construction, and support for RS485 Modbus RTU, 4–20 mA, and pulse outputs for hospital BMS integration.

Results:

• Continuous, high-confidence visibility of oxygen flow across all locations
• Early detection of abnormal consumption patterns
• Reduced risk of undetected oxygen supply variations
• Enhanced patient safety through accurate low-flow monitoring
• Compliance with stringent medical infrastructure requirements
• Data-driven decision-making enabled through digital outputs
