What counts: Transformer safety
The MESSKO® MFLOC 2.0 flow indicator detects pump failure in a transformer’s oil and water cooling circuit immediately and reliably. A specially-designed spoonshaped paddle made of fiberglass-reinforced plastic is positioned in the cooling circuit as flow resistance to monitor the coolant flow. If the pump is active, the coolant flows against the paddle, and it is pressed reliably against the end stop with both laminar and non-laminar (turbulent) flows (starting at flow rates as low as 0.70 m/s).
The MESSKO® MFLOC 2.0 uses a patented magnetic coupling to translate the movement of the paddle into rotary movement on the indicator. Two securely installed micro-switches changeover contacts) signal the pump status.
The long service life of a transformer
The MESSKO® MFLOC 2.0 flow indicator has all the usual MESSKO quality features. The cast aluminum housing is extremely robust and weather-resistant. Moreover, an offshore version is optionally available. The watertightness of the cooling circuit is guaranteed thanks to separation of the sensor and the indicator. This means that if the indicator becomes defective, it can be replaced while the transformer is still in operation.
The MESSKO® MFLOC 2.0 is designed for use at an ambient temperature of -40 °C to +80 °C and at a coolant temperature of -30 °C to +120 °C. The viewing glass, made of laminated safety glass, has an integrated UV filter.
These quality features ensure reliable function and unobscured readability of the indicator over many years.
