The measured input signals are evaluated for internal recording and control. - 2-channel flow measurements - Flow control - Pump control - Monitored dual tank measurement - Event recording - Data recording Applications The instrument can be interfaced simultaneously with up to four 4-20 mA or 0-5 V analog and four digital sensors performing measurements and computing parameters such as: Level, volume, open channel flow, temperature, pH or pressure. The instrument provides a supply voltage 24 V/0.5 A as power supply for the sensors. The output signals from each connected sensor are adapted and evaluated. The instrument can be programmed with various set points resulting in 2 analog outputs and 2 digital outputs or 6 relays. Complex switching sequences are possible and a pump rotation for even wear can be configured. As a recorder, the instrument is capable of storing as much as one-month’s data at one-minute intervals or more than a year’s data at 15-minute intervals, logging all data channels. The longest adjustable time interval is 99 minutes. Parameters Units with analog output 4-20 mA such as level, pressure, pH and temperature meters can be converted to their respective functions like volume/ level, flow rate, pressure, acidity and temperature by using one of the preprogrammed conversion formulas or via a custom set points table. When a 2-wire powered ultrasonic level transmitter is connected, the DataControl 2500 can be set to interpret the signal as percentage, distance / level, volume or flow. Conversion formulas for different types of tanks, weirs and flumes are stored in the memory to easily configure volume & flow applications; alternatively a 35 point custom table can be used. Addition, subtraction and averaging can be made via the unit. Totalizer functionality is provided for each channel.

The configuration is password protected. Using a personal computer and the custom software supplied with the unit, the instrument can be configured and all recorded data can be displayed in graphical or alphanumerical format. The recorded data can also be exported for further analysis in .csv format. Data logging and communication • Independently programmable inputs • Preprogrammed conversion formulas • Programed custom set point table • Remote configuration and data retrieval • Programmable control functions • Programmable measurement functions • Data can be exported to PC • Two Megabyte flash based storage • Remote data retrieval • RS232 / RS485 network operation • Modem / GSM modem interface • Firmware can be updated in the field Remote communication with the instrument is possible using RS232/RS485, modem or GSM modem (data & SMS). Via this interface, configuration changes and data retrieval are possible. Using the RS485 interface, a network of up to 32 DataControl 2500 can be created. RF telemetry is easily implemented by adding an external RF transceiver. UF_DC2500_DB_02_0901.doc Reprint of texts or text extracts requires prior written authorization of Badger Meter Europa GmbH.
