		Flow-Tronic TORPEE-MAG Full Pipe Averaging Magflow Meter (Insertion Type) The TORPEE-MAG is a hot tap full profile electromagnetic averaging insertion flow meter. Multiple electrodes (as many as 7x2) placed across the entire sensor body at equal area, measure & report the average flow rate over the full diameter of pipe. With every pair individually calibrated, the specific design of the multielectrode sensor compensates for variable flow profiles, including swirl & turbulent condition. Insertion type magflows benefit from low installation costs and short lead-times (as little as 6 weeks) as opposed to comparitively sizeed flow through units - the bigger the pipe the bigger the savings! Suitable for drinking & raw water Measuring Principle: Electromagnetic No straight lengths needed - mount close to bends / Tee's / valves Hot tap insertion up to 17 bar for removal without process interruption! Measuring Range: 0 » 6m/sec Accuracy: ± 0.5% of reading Application: full pipes from DN100 » 4000 Max pressure 16Bar Power: suitable for battery (IoT) installations Ingress: IP68 Process conn: 1, 1½ & 2" available Options: TMC-20 converter with Modbus RTU, pulsed and 4-20mA output TMC-15 converter battery powered w/ 6 x D cell batteries See how it works - YouTube Back to top	Flow-Tronic TORPEE-MAG - Datasheet (2024_11) (PDF) Flow-Tronic TMC-20 - Datasheet (2025_01) (PDF) Flow-Tronic TMC-15 - Datasheet (2023_04) (PDF) Flow-Tronic TORPEE-MAG - Brochure (2022) (PDF) Flow-Tronic - TMC-20 controller (JPEG) Flow-Tronic - TMC-15 controller (JPEG)
