Drain Gauge G3 AutoPump

When measuring deep drainage there are often times when there may be higher volumes of drainage. Because the Drain Gauge G3 captures all drainage in the measurement area, the sample reservoir often becomes full. If water is not removed from the resevoir before it collects 61 mm of drainage, water will come into contact with the wick. If this occurs, sample water can be pulled out of the reservoir due to capillary rise, resulting in an under estimation of deep drainage.

We designed the AutoPump with these remote and high drainage sites in mind.  It automatically drains the Drain Gauge G3 reservoir into additional bottles on the surface for later collection or into the field at a point away from the measurement area.

Drain Gauge Sensor

We recommend using the additional temperature, depth and conductivity DG Sensor to measure cumulative drainage. Without using the sensor, only manual measurements of cumulative drainage can be made with the Drain Gauge. This sensor will allow you to get the data you need, and know when it is time to take a sample from the reservoir. DG Sensors can be added as an accessory to new units or easily installed on G3 Drain Gauges already in the field.
