Hydrostatic level indicator: optimal consumption control in battery tanks
August 2008
Level Measurement & Control
The new Level Indicator TankControl 01ZT from Afriso-Euro-Index is designed for the continuous level measurement and the reporting of level differences in interconnected fuel oil and diesel tanks (eg, battery tanks) with heights from 0,9 to 3 m.
The measuring system consists of the evaluation unit with graphic display as well as two submersible sensing probes. When a pre-selected and fully adjustable minimum or maximum liquid level is reached, a visual and audible alarm (with built-in mute facility) is given by the evaluation unit.
Two submersible probes warn of a faulty or suspect interconnection between battery tanks
When a pre-selected adjustable level difference between probe No.1 and probe No.2 is reached, an alarm signal is also initiated. This will show up a possible faulty or suspect interconnection between the battery tanks and reduces considerably the risk of overfilling a tank. The liquid levels in the tanks are measured daily, memorised and converted. This facilitates an excellent check on levels of consumption. The consumption history can be displayed over a period of up to five years.
A graphic display gives a quick, easy-to-read overview of consumption, tank contents and an estimated forward fuel coverage of the existing fuel stock. Commissioning of the instrument is simple and quick with menu-guided instructions. The hydrostatic Level Indicator TankControl 01ZT requires a 230 V a.c. supply; two change-over relays are incorporated for further switching functions or for connection to remote event reporting systems such as Afriso EMS 220 or EMS 442.
