Water Flow Monitoring Equipment & Parts
Accurate, Reliable Flow Measurement for Industrial Water Systems
Effective water treatment depends on accurate measurement and control. Monitoring flow is central to achieving that. AllWater Technologies supply a complete range of water flow monitoring equipment for industrial and commercial applications. From low-cost inline meters to high-precision digital monitoring systems, our products help maintain performance, ensure compliance, and support long-term system health.
Whether you need a single flow meter or a complete instrumentation package, we offer tailored solutions designed to meet your process and operational requirements.
Our Flow Monitoring Range
Industrial Flow Meters
We offer a wide selection of industrial flow meters designed for clean water, greywater, and aggressive fluids. These meters are suitable for measuring flow in everything from ultrapure water production to wastewater discharge lines.
Meter types include:
- Turbine Flow Meters: Ideal for clean, low-viscosity fluids. High accuracy and fast response.
- Electromagnetic Flow Meters: Suitable for conductive liquids. No moving parts, low maintenance.
- Ultrasonic Flow Meters: Non-intrusive clamp-on models for temporary or permanent installations.
- Variable Area (Rotameter) Meters: Simple, cost-effective visual indication of flow rate.
Our flow meters are available in multiple sizes and configurations to match your line pressure, flow rate, and pipe material.

Low Cost Flow Meter Options
For projects where affordability is key, we offer low cost flow meter models without compromising on durability or accuracy. These are ideal for:
- Smaller-scale water treatment installations
- Mobile or temporary systems
- Pilot plants and R&D setups
- Utility rooms and low-flow applications
Our economical solutions come in both mechanical and digital options and are supported with full documentation for installation and calibration.
Flow Sensors and Switches
In addition to flow meters, we supply inline and insertion-type flow sensors and switches that integrate with digital control systems. These allow automated control of dosing, filtration, or pump systems based on real-time flow data.
Sensor options include:
- Paddlewheel and Hall Effect sensors
- Vortex and thermal mass flow sensors
- Dry contact flow switches for alarm or interlock systems
All sensors are compatible with PLCs, SCADA systems, and control panels and can be integrated into new or existing infrastructure.

Telephone & remote diagnostics for rapid fault identification

System troubleshooting and root cause analysis

Planned service visits tailored to your production schedule

Guidance on optimisation, upgrades and retrofit options

Ongoing training and user support post-installation

On-site engineering support from qualified specialists

Water System Support: Frequently Asked Questions
A flow meter provides a direct measurement and display of flow rate, while a sensor typically outputs a signal to a control system. Flow sensors are often used where space is limited or remote data logging is required.
Yes, we offer models for both clean water and solids-bearing wastewater. The right choice depends on your fluid type, temperature, and pressure conditions.
Not always. Some meters are connected directly to PLCs or SCADA systems. However, we do supply integrated or panel-mounted displays if required.
This depends on the meter type and usage, but we recommend annual calibration checks for most critical applications.
Yes. We offer chemically resistant materials and low-flow models ideal for dosing systems. Please speak to our team to match a meter to your specific chemical.
