Optional module for water testing on sewage manholes/pipes in accordance with EN 1610 in conjunction with the EDS2 level probe and smart memo. In the event of a drop in level during the test, the smart level control automatically tops up the test area with water to maintain the initial level. The amount of water added is automatically measured and the measured value is sent to the smart memo. The smart level control is connected to the smart memo via an additional B11 termination cable. A container for use as a water reservoir should be positioned at least 0.5 metres above the smart level control and connected to it via a hose.
