www.nokeval.com sales@nokeval.com 2022TANK Level and volume indicator • Available for panel or wall mounting • Process input 0/4..20 mA, 0..5/10 V • 10 point linearization gauge signal to level • 32 point linearization level to volume • 6-digit LED display • Configuration via front panel keys or serial port • 2 or 3 alarm relays • Serial communications RS-232 and RS-485 • Wide power supply range 85..240 VAC or 12..32 VDC / 24 VAC • Case protection rating IP65 2022TANK indicator is designed for liquid tank applications. It is connected to a tank level transmitter with a mA or V signal. The indicator can feed a level transmitter with a 24 V 150 mA supply. This mA or V signal is linearized to a level reading using up to ten free linearization points. They are mA - level pairs. Any of the points can be edited afterwards. The level can be expressed in any unit, e.g. mm or m or inches. Liquid volume is then acquired from the level reading using up to 32 free linearization points. These are simply level - volume pairs. Again, the volume can be expressed in any unit. The six-digit display allows displaying readings up to 999 999. The indicator can be configured using the front panel or alternatively using a serial connection and a free software Mekuwin. The serial connection allows to read the level and volume using Nokeval SCL protocol, whose specifications are available to everyone. The serial connection is on an option card. The meter can be equipped with two or three alarm relays using an option card. This meter is a part of the 2000 series. It is available as a 96x48 mm panel meter with 14 mm digits (2022TANK) or in a wall-mounted IP65 enclosure with 20 mm digits (28002022TANK). Blink Serial
