The VS series of vacuum systems from UMS are capable of applying a constant or tension-controlled vacuum for long-term monitoring projects.
The constant vacuum method is continuously maintained by a regulated vacuum pump. The vacuum can be set between atmospheric pressure and 85 kPa.
A tensiometer measures the soil water tension. The programmable vacuum station VS automatically supplies a vacuum in correspondence to the measured tension. Due to the numerous functions of the unit, an optimal adaptation to the sampling task is possible.
