The PD6938 ProtEX+ pulse input flow rate/totalizers can be installed in a variety of areas (hazardous, dirty, wet, corrosive, hot, or cold) to provide convenient and informative display of flow rate and total from any pulse output flowmeter. These instruments will accept a variety of pulse inputs, including slow pulse rates. They can be powered from a battery, 9-30 VDC, or the 4-20 mA output loop, have on-board datalogging capabilities, come with explosion-proof approvals, and can be ordered with optional 4-20 mA output and two relays.
The ProtEX+ carries all major approvals including:
• UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
• CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
• ATEX and IECEx Certified as Explosion-Proof
The PD6938 can operate down to -40°C and is certified by the agencies to be installed in areas that get as cold as -55°C.
The PD6938 ProtEX+ is available in aluminum and stainless steel enclosures that are designed for easy use and installation. The process connection is available in M20, 3/4" NPT and 1" NPT and there are two other conduit holes for field wiring.
Free, PC-based, MeterView XL software that connects to the meter via a micro-USB cable is available for programming and setup of the instruments. Four CapTouch through-window buttons are available to operate the instrument without removing the cover.
All models come equipped with two open collector outputs and a digital input. There are also models available with Modbus RTU RS-485 communications, two solid-state relays, and isolated 4-20 mA analog output options.
