Industrial magmeters
The SM family of industrial magmeters are available in many pipe sizes, process connections, and flow rates. Outputs include digital and analog. All SM magmeters include a totalization feature. Magmeters with totalizer functions calculate and accumulate the total volume of fluid passing through the meter over a specific period. The totalizer function is used for applications requiring precise fluid monitoring and control or detailed accounts of total fluid volume such as batching operations.
