2. GENERAL
Built around a single-chip microprocessor, this multifunction counter is designed lightweight and compact.
It offers four display functions (cumulative total flow, hourly and per-minute instantaneous flowrate, and
resettable total flow) in a single unit along with a factored pulse output.
A 4-20mA DC and 1-5V DC flowrate output plus high/low alarm output are available as an option (Model
EL0122 only).

4.1 Installation Location
(1) Select a location free from mechanical vibration and corrosive gases.
(2) Select a location maintained at room temperature with least temperature variation and free from
moisture.
We guarantee that the counter is operational at ambient temperatures from
-10 to +50℃,
but we recommend an installation location where the temperature is controlled to the room
temperature.
(3) Provide a sufficient working space behind the counter to facilitate electrical connections and
maintenance.
4.2 Installation
(1) This counter is designed for panel mount.
(2) Mount the counter as follows:
①
Remove panel-mount fittings from the counter and front mount the counter through the opening
cut in the panel.
