How to Select Instruments for Water & Wastewater Industry – Simplify Your Instrument Selection
Created on 07.10
The water and wastewater industry covers municipal water supply, sewage treatment, industrial wastewater treatment, circulating water and other application scenarios. Varying site conditions and measurement requirements demand differentiated instrument performance standards.
Given complex working conditions, instrument selection must be customized based on medium characteristics, installation constraints and practical measurement demands to deliver an optimal measuring solution.
1. Working Conditions & Commonly Used Instruments in Water & Wastewater Industry
The water and wastewater sector includes municipal water supply, sewage treatment, industrial wastewater treatment, water purification equipment and other sub-sectors, each with distinct measurement standards.
Different instruments are deployed according to specific process requirements in engineering projects:
- Pressure Transmitters: Monitor operating pressure of pipelines, pump stations, filtration equipment and other facilities;
- Level Instruments: Continuously measure liquid level in water tanks, storage vessels, regulating tanks and other containers;
- Flow Meters: Calculate medium flow volume and support process automatic control;
- Water Quality Analyzers: Including pH meters, conductivity meters, dissolved oxygen analyzers, turbidity meters and other devices for real-time water quality parameter monitoring.
Each instrument undertakes independent measurement tasks. Rational instrument configuration tailored to on-site working conditions guarantees long-term stable operation of water treatment systems.
2. Core Factors to Consider for Water & Wastewater Instrument Selection
Water treatment sites are generally exposed to high humidity, corrosive media and solid particle interference. Measuring range alone cannot serve as the only selection standard; comprehensive evaluation of medium properties, installation mode and operating environment is mandatory.
For conventional working conditions such as clean water and water tanks, measurement stability is the primary concern. For challenging environments including sewage and industrial wastewater, priority should be given to corrosion resistance, anti-interference capability and long-term operational reliability.

3.2 Liquid Level Monitoring for Water Tanks & Basins – Norhen Submersible Level Transmitters
Submersible level transmitters represent the mainstream measuring solution for clean water basins, storage tanks and liquid storage vessels.
Norhen Submersible Level Transmitters realize continuous liquid level detection by measuring hydrostatic pressure of liquid media, with simple installation and consistent operational performance.Applicable scenarios:
- Liquid level monitoring of domestic & industrial water tanks
- Automatic level control for clean water basins
- Level measurement of liquid storage tanks
For long-term submerged measurement scenarios, the transmitters output stable continuous signals to provide credible data for automatic control systems.(Embedded link for product images)
3.3 Level Measurement for Harsh Working Conditions – Norhen Radar Level Gauges
Sewage tanks, regulating basins and industrial wastewater storage tanks often contain suspended solids, foams and corrosive media, which easily impair the performance of conventional contact-type measuring instruments.
Norhen Radar Level Gauges adopt non-contact measurement without direct medium contact, effectively eliminating damage caused by sewage and corrosive fluids.With stable measuring performance and low maintenance frequency, radar level gauges are ideal for:
- Liquid level monitoring of sewage treatment tanks
- Level detection of industrial wastewater storage tanks
- Level measurement under high-temperature, corrosive and other harsh environments
Conclusion
Instrument selection for water and wastewater industry relies fully on actual on-site working conditions. Appropriate measuring solutions for pipeline pressure monitoring, water basin and sewage tank level detection improve system stability and cut long-term maintenance costs.
