DL Series - Dual-Line Analog Input Process Meter
The DL Series analog input process meter is a multi-purpose, easy-to-use digital process meter ideal for level, flow rate, temperature, or pressure transmitter applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V). Three of the front panel buttons can be custom-programmed for a specific operation. The analog input can be scaled to display the process in two different scales; for example, the main display could indicate level in feet and the second display could indicate the volume in gallons.
