Flow Rate Totalizer Current (4-20 mA)

Flow Rate Totalizer
Precision Digital’s flow rate/totalizers display the flow rate from either an analog or pulse output flowmeter as well as the accumulated total and grand total volume over time. Relay, open collector, and analog outputs combined with a variety of power options including AC, DC, battery and loop-power allow these rate/totalizers to provide versatile flow measurement solutions for almost any environment. Rate/totalizers are available in NEMA 4X front digital panel meters as well as UL, CSA, ATEX, and IECEx approved explosion-proof and intrinsically safe meters for hazardous areas.

Flow Rate Totalizer Current (4-20 mA)

  • The Loop Leader PD6620 is an ATEX and IECEx approved, UL listed, intrinsically safe and nonincendive, loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, loop-powered backlight with a unique red backlight option for alarm conditions, and optional bargraph display (PD6628) provide a clear and attractive presentation of the process. All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features. 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 Loop Leader loop-powered rate/totalizer is built in a shallow-depth case with a IP65 front and features loop-powered backlighting and a wide -40 to 158°F (-40 to 70°C) operating temperature range. It doesn't matter if it's in hazardous areas, 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.

    Why you should buy:
  • Go with the Helios PD2-6262 when you want to display two 4-20 mA flowmeter inputs on one meter. Both of these inputs can be displayed on six full digits and each flowmeter is provided with its own 24 VDC power supply. The PD2-6262 can also perform a variety of math functions on those two inputs, such as computing the difference between them or summing them together. One application for the PD6262 is determining fuel consumption by computing the difference between two flowmeter inputs.

  • The ProtEX-MAX PD8-6262 offers all the functionality of the ProVu PD6262 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is specifically designed to display flow rate and total from two (2) analog output (4-20 mA, 0-5 V, 1-5 V, etc.) flowmeters. It displays these signals on a dual-line, 6-digit Sunbright sunlight readable display. The two display lines can be used to show both flow rates simultaneously, to alternate between the two inputs showing both the flow rate and total of each, or to show the result of math functions performed on the flow rates and totals. The total overflow feature allows up to 9-digit totals and grand totals to be displayed. The PD8-6262 can be equipped with four internal relays and a 4-20 mA analog output. It can be programmed and operated without opening the housing by using the built-in CapTouch through-glass buttons or the RS-485 serial communication port with free Modbus protocol.
