Apparatus for water sampling
First Claim
1. A buoyant apparatus for water sampling comprising:
- (a) buoyant container (10) capable of being closed watertightly;
(b) in said container, an electric motor (3) and a battery (7) for supplying power to said electric motor;
(c) a pump (2) mounted to said container and driven by said electric motor, said pump having a suction side and a pressure side;
(d) connected to the suction side of said pump, means (6) for communicating with a sampling point;
(e) connected to the pressure side of said pump, means (5) for communicating with a sample receiver; and
(f) in the container, a control unit (8) controlling the operation of said electric motor;
wherein said control unit (8) is programmable to run said electric motor (3) and pump (2) during certain run times at specific intervals for taking samples.

Abstract
The invention relates to an apparatus for water sampling. The invention relates to such a water sampling apparatus that permits intake of so-called composite samples as well as individual samples from different depths of water. The apparatus comprises a sampler (2) driven by an electric motor (3) and placed into connection with a buoyant container (10). The sampler is preferably a centrifugal pump (2) placed into connection with the container (10). The suction side of the pump (2) communicates with the sampling point and the pressure side communicates with a sample receiver. The sampler (2) is arranged to operate under control of a control unit (8) for taking samples of specific volume at specific intervals. The control unit (8) is placed inside said container (10). The electric motor (3) is powered by an accumulator (7) placed preferably inside the container (10).
