The Precision Digital Loop Leader PD6620 is a reliable flow rate and totalizer meter, perfect for tough process control tasks. Its loop-powered design means it operates efficiently without needing extra power lines. Setting up and programming the meter is easy, thanks to the four user-friendly buttons on the front panel.
This meter features a dual-line display that shows five digits on the top line and eight digits on the bottom line. It comes with preprogrammed engineering units and an optional bargraph display (model PD6624) for a clear view of your process data. You can easily switch between units of measure, such as gallons per second to liters per second, without having to re-scale the meter.
The display can be tailored to meet your specific needs. Typically, the top line shows the flow rate, while the bottom line can display the total, grand total, or engineering units. With three programmable function keys and a digital input, you can customize the meter for specialized applications.
Every model includes two open collector outputs and can be equipped with two solid-state relays and a 4-20 mA analog output. These outputs are versatile and can be programmed for various functions, including alarm notifications, signal retransmission, and pump control.
Thanks to its loop-powered feature, the Loop Leader PD6620 eliminates the need for expensive power installations. It is housed in a shallow-depth case with an IP65 rating, ensuring durability in various environments. The meter operates effectively in a wide temperature range from -40 to 167°F (-40 to 75°C). Whether used indoors or outdoors, in bright sunlight or dim conditions, and in wet or dirty environments, the Loop Leader is built to perform anywhere.
