Functions

Non-invasive measurement (clamp-on) – no need to cut the pipe or stop the system
High accuracy up to ±0.5% – suitable for professional use
Water resistance (IP68 sensors) – can be used in harsh conditions
Universal power supply – AC and DC options
Digital control – clear data display and analysis
Flexible installation – wall-mounted, panel-mounted or integrated

Usage

For home users: monitoring water consumption at home, flow control in heating systems (e.g., underfloor heating), optimization of water pump operation
For engineers / project managers: analysis of building engineering systems (HVAC, water supply), energy efficiency projects, temporary measurements without system disassembly
For electricians / installers: quick installation without pipeline modifications, diagnostics and system testing, suitable for modernization projects
Industry: monitoring liquid flow in production, control of chemical or technological processes, analysis of water supply and wastewater systems

Advantages

No need to cut the pipe – fast installation
High accuracy (up to ±0.5%)
Waterproof and resistant to harsh conditions (IP68)
Suitable for hot liquids
Universal power supply
Durable materials

Disadvantages

Requires proper sensor installation (accuracy depends on installation)
Not suitable for very low flows (<0.1–0.3 m/s)
Requires basic technical knowledge for configuration
