The Loop Leader PD684 is a loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications.
The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop.
The PD684 loop-powered rate/totalizer is built in a shallow-depth case with an FM Type 4X front and features loop-powered backlighting and a wide -30° to 65°C operating temperature range.
It doesn't matter if it's indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
