Tek-Trol 7803A-AP0 - The Tek-LCD 7803A is a plastic, field-mounted flow rate/totalizer that can display flow rate and total from a pulse output flow meter. Its display has a five digit upper line for rate, a seven alpha-numeric character lower line for total, and comes standard with a backlight. The Tek-LCD 7803A is built in a NEMA 4X and IP65 rated plastic enclosure which can stand up to even the harshest environmental conditions. It can be powered from an included battery or a 24 VDC external power supply. Some features that really make the Tek-LCD 7803A stand out are its automatic unit conversions from flow meter k-factor units, ability to log up to 1024 data points, and SafeTouch® through-window buttons. These buttons allow the Tek-LCD 7803A to be programmed and operated through the cover window, thus eliminating the need to remove the cover in dirty or wet environments.
