The FlowMaid™ is a small monitoring device used to record level, flow, volume and discrete events. It calculates the volume lost in a SSO event using the Manning equation. As an open channel flow meter, the user can select from 11 flow formulas.
The only requirement is to enter the level of the overflow pipe, its diameter, material and angle. Years of data can be recorded before filling its memory. Every event shows start and end time, duration, average flow and volume lost.

The relay output can be remotely activated or based on events such as high level. For an optimum operation time on batteries, the relay output can be used to interrupt the power supply of the level sensor or other accessories like a cellular modem.

Level Monitor and open channel flow meter

The user can use one of the following formulas (pictures are in same order) : Manning, Manning for open channel, California pipe, Rectangular weir with end contractions, Rectangular weir without end contractions, V-notch (or triangular) weir and Trapezoidal (or Cipolletti) weir or use a standard or polynomial flow formula or a lookup table.
