Yokogawa’s ADMAG TI - AXG magnetic flowmeter (magmeter) with EtherNet/IP is used to measure the water moving from the pump to the snow cannons. The accurate measurement allows the operator to monitor and control the water in the mixture to produce artificial snow with the perfect consistency.


Accurate and durable magnetic flow meters (magmeters) were difficult to maintain in the process as the corrosive and abrasive nature of the process degraded their operation. That led to leaks that not only reduced the flow but also contaminated the product and the magmeters. Since Sigura maintained strong vigilance, the company needed to replace some magmeters monthly...
