The PD6262 is a member of the ProVu series of 1/8 DIN digital panel meters that 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 display that is available with optional Sunbright® sunlight readable LEDs. The dual-line display 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. Like all ProVu meters, the PD6262 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. ProVu meters can be equipped with up to four internal relays, a 4-20 mA output, and Modbus® RTU serial communications. The PD6262 dual-input flow rate/totalizer includes a 24 VDC power supply to drive the flowmeter and can be programmed via the front panel pushbuttons or free MeterView® Pro software.

Differential Pressure Flow (PD6262)The PD6262 can display flow rate and total by extracting the square root from the 4-20 mA signal from differential pressure transmitters. The user selectable low-flow cutoff feature gives a reading of zero when the flow rates drop below a user selectable value.
Weir Flow Calculated Using Exponential Signal Input Conditioning
Open Channel Flow (PD6262)The PD6262, in combination with ultrasonic level transmitters, makes for an economical way to measure and display open channel flow rates and totals in most weirs and flumes, and take periodic samples. All the user needs to do is enter the exponents for the weirs or flumes into the PD6262 and the PD6262 automatically raises the input signals to those powers. Sampling can be based on the total flow or the flow rate. Each channel's signal input conditioning is programmed independently.
Convert Pulse to 4-20 mA (PD6363)The PD6363 accepts pulse outputs from flowmeters and with the appropriate option installed, can convert the pulses to a 4-20 mA signal. The 4-20 mA signal can be programmed to correspond to either the flow rate or the total flow.
