Suitable Applications
The TIM | TI3M Series is well suited for industrial systems that need both local indication (flow + total) and automation-friendly outputs, especially on larger pipes where insertion sensors simplify installation. The availability of pulse + 4–20 mA outputs supports a wide range of monitoring and control architectures.
- PLC/DCS integration using 4–20 mA for flow rate and pulse for totalization
- Process and utility water measurement across ½”–24″ lines
- Chemical transfer/distribution systems requiring material flexibility (PVC/PP/PVDF/316 SS)
- OEM skids and packaged systems needing local LED indication plus analog output
- Retrofit projects benefiting from insertion installation fittings (tees, saddles, weld-on/glue-on adapters)
- Industrial applications requiring long-life rotor design with minimal maintenance
