Introduction

The ProtEX-MAX PD8-6363 is an explosion-proof dual pulse input rate/totalizer ideal for flow rate, total, and flow control applications. The totalizer features a dual-line display, with a main display of 0.60" (15 mm) high, and a second display of 0.46" (12 mm) high superluminous LED digits, which can be read in any lighting condition, including direct sunlight. The totalizer is housed in a field-mountable, NEMA 4X/IP68 rated enclosure available in either aluminum or stainless steel for convenient indoor and outdoor installation.

The totalizer accepts a wide variety of pulse signals from two (2) pulse output flowmeters that can be displayed as flow rate, total and grand total. The rates, as measured by the flowmeters, are automatically aggregated into cumulative totals and grand totals which can be displayed with the rates.

Various math functions may be applied to the rate, total, and grand total of the two channels, including addition, difference, absolute difference, average, weighted average, multiplication, division, minimum, maximum, draw, ratio, and concentration.
The displays, relays, and the analog output may be assigned to the rate, total, or grand total of input channels A or B, or math result channel C. Three of the programming buttons can be set for custom operation.

A fully loaded ProtEX-MAX PD8-6363 dual-input flow rate/totalizer comes with four SPDT relays, a 4-20 mA output, five digital inputs and four digital outputs, and RS-485 serial communications. The four relays can be used for alarm indication or process control applications. The 4-20 mA isolated output, Modbus RTU serial communications, and digital I/O features make the ProtEX-MAX an excellent addition to any system.

ATEX/IECEx Specific Conditions of Use:
  1. The equipment label and epoxy coating may generate an ignition-capable level of electrostatic charges under certain extreme conditions. The user should ensure that the equipment is not installed in a location where it may be subjected to external conditions (such as high-pressure steam) which might cause a build-up of electrostatic charges on non-conducting surfaces. Additionally, cleaning of the equipment should be done only with a damp cloth.
  2. Flameproof joints are not intended to be repaired.
  3. All entry closure devices shall be suitably certified as “Ex d”, “Ex t” and “IP66/68” as applicable. Suitable thread sealing compound (non-setting, non-insulating, non-corrosive, not solvent based, suitable for the ambient rating) must be used at the NPT conduit entries to achieve the IPx8 rating while maintaining the Ex protection concept.

Applications


Differential Pressure Flow (PD6262)

The PD8-6262 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.

  • Display Flow Rate
  • User Selectable Low-Flow Cutoff
  • Only 2 Calibration Points Required


Open Channel Flow (PD6262)

The PD8-6262, in combination with ultrasonic level transmitters, makes for an easy and convenient 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 PD8-6262 and the PD8-6262 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.



Weir Flow Calculated Using Exponential Signal Input Conditioning


Convert Pulse to 4-20 mA (PD6363)

The PD8-6363 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.

  • Use K-Factor or Multi-Point Scaling
  • ProVu Powers the Flowmeter
  • Up to 3 Analog Outputs
