PanaFlow™ MV80 & MV82 User’s Manual 7
Chapter 1. Introduction
1.6.2 Line Size, Process Connections and Materials
The MV80 In-line model is built for line sizes ½ through 4 inch wafer or ½ through 8 inch flanged design using
ANSI 150, 300, 600, PN16, 40, or 64 class flanges.
The MV82 Insertion model can be used in line sizes 2 inch and greater and is built with a compression fitting or
packing gland design using 2 inch NPT, or 2 inch flanged connections (ANSI 150, 300, 600, PN16, 40, or 64 class
flanges). The packing gland design can be ordered with a permanent or removable retractor.
The MV80 In-line model can be built with A105 carbon steel, 316L stainless steel, or Hastelloy C-276. The MV82
Insertion model can be built with 316L stainless steel or Hastelloy C-276.
1.6.3 Flowmeter Electronics
PanaFlow flowmeter electronics are available mounted directly to the flow body, or remotely mounted. The electronics
housing may be used indoors or outdoors, including wet environments. Available input power options are: DC loop
powered (2-wire), DC powered or AC powered. Three analog output signals are available for your choice of three of
the five process variables: mass flow rate, volumetric flow rate, temperature, pressure or fluid density. A pulse output
signal for remote totalization and MODBUS or HART communications are also available.
PanaFlow flowmeters include a local 2 x16 character LCD display housed within the enclosure. Local operation and
reconfiguration is accomplished using six push buttons operated via finger touch. For hazardous locations, the six
buttons can be operated with the electronics enclosure sealed using a hand-held magnet, thereby not compromising the
integrity of the hazardous location certification.
The electronics include nonvolatile memory that stores all configuration information. The nonvolatile memory allows
the flowmeter to function immediately upon power up, or after an interruption in power. All flowmeters are calibrated
and configured for the customer's flow application.
