How It Works
Max P-Series Precision Flow Meters are positive displacement piston meters that are able to operate over a wide range
of ow rates and uid viscosities. High accuracy measurement is achieved through precision machined radial pistons
that move proportional to the ow. High resolution outputs are produced by measuring the direction and speed of the
pistons and converting the signals to analog or frequency outputs. Flows can be monitored from 0.005 cc/min up to 35
liters/min with uid temperatures from -40°C to 225°C and pressure ratings of 250 psi (17 bar), 3000 psi (210 bar), and
7250 psi (500 bar) depending upon the model. The industrial meter electronics are protected against water, dust, and
most corrosive liquids. The 5-pin Turck connector provided is IP68.
Additionally, IP66 rated explosion proof enclosures,
combined with a choice of one-part and two-part, high temperature designs with remote electronics cover a wide
range of application environments – from the laboratory to harsh industrial processes.
Optional seal materials allow for
different uid compatibility.
Max Machinery, Inc. designs, manufactures, calibrates, and refurbishes high accuracy, high resolution, precision liquid
ow meters under an ISO 9001:2015 certied quality management system. All Max Precision Flow Meters are tested
and calibrated in our lab and provide measurements traceable to NIST. If your calibration certicate is lost or missing,
contact MMI with your meter serial number for a copy.
P-Series User Manual Rev2022 2
Your Max Flow Meter has been congured at the factory to be used out of the box based on your submitted application
data. Plumb it, wire it, and use it. The following section will provide instructions on how to properly plumb your Max Flow
Meter in the liquid lines of your application.
Use the “IN” port or follow the ow direction arrow markings for the primary ow direction. Install the meter on the
discharge side of the pump whenever possible. Excessive vibration at the meter should be avoided.
Orientation: Preferred mounting orientation of the meter depends on meter type. The orientation optimizes air purging
and/or minimizes heat transfer to the electronics. P-Series meters with in line ports prefereably mount with the
transmitter facing down or alternately on the side. P001 and P002 with offset ports mount with the transmitter facing
up. These mounting orientations prevent air in the system that can cause response delays and errors in measurement.
NPT ttings: Always use pipe sealant or pipe tape to install ttings, and leave the rst thread of pipe exposed. Ensure
the tape or sealant does not accidentally enter the meter.
SAE / BSPP ttings: Always use process uid compatible lubricant on the o-ring to attach the tting to the meter.
Compression Fittings: P001 compression ttings are based on Swagelok style ferrules (see g. 1). Do not use other
manufacturer’s parts because the sealing angle may not be the same. Fitting kits contain detailed instructions and
are shipped with every meter (contact Max Machinery for spare ferrule kits). Always torque to values on tting kit
instructions. Select tubing grades that meet or exceed your system pressure requirements. If using exible tubing,
install a tubing insert to allow compression ferrules to seal (suggested inserts: Swagelok SS-405-2, SS-405-03 or SS-
405-170). To reuse a tube tting, mark the nut and meter before removal. When re-installing, tighten to align the marks
then tighten a quarter turn farther.

Bypass Valves: Install valves to allow system start-
up, lter replacement, or ow meter removal without
completely shutting the system down and draining the
lines. See diagram.
Failure to use a bypass at start up may lead to ow meter
damage due to debris, overspeeding the meter with air in
the lines, and pressure shock due to initial line surges.
Filtration: A 5 micron lter is recommended on the inlet for the P001 ow meter. A 10 micron lter is recommended on
the inlet for all other P-Series ow meters. If measuring bi-directional ow, a lter should be installed on both sides of
the ow meter. Materials with brous or non-abrasive particulate matter may need to be run without lters.
Clean Plumbing: Before installing the ow meter, the system lines shall be cleaned and free of all debris or
manufacturing particulates. Purging lines with compressed air or steam are typical cleaning methods. Do not use
compressed air or steam on the Max ow meter, damage will occur.
High Temperatures: Orient your meter so the transmitter is to the side
or below to minimize heat transfer by convection from the ow meter
to the transmitter. The transmitter is the most heat sensitive element
in the system. Consult the chart on page 8 for specic limits on
uid and ambient maximum temperatures. When operating in the
upper temperature ranges, always insulate the meter but leave the
transmitter housing exposed so it radiates heat. An optional heater
block can be used on the ow meter to keep it at the uid operating
temperature. For substances solid at room temperature, a heater
block may be required to keep material molten to ow through the
meter.

Mechanical - Operation
Determine that the following parameters of your ow metering system are within the specications for the specic
meter being used:
Maximum System Pressure (Specications)
Differential Pressure across meter (Pressure Drop Curves)
Maximum Flow Rate (Pressure Drop Curves)
Metered Fluid Temperature (Sales specication, transmitter specications page 8)
If the metered uid is greater than 28°C (80°F) over ambient, see the “High Temperature Start Up” section below.
With valves (#1) and (#2) closed, slowly open valve (#3) (bypass) to clear the lines of foreign particles and air.
Slowly open the inlet valve (#1). Slowly open the outlet valve (#2). Completely close the bypass valve.
No routine maintenance, cleaning, or lubrication of the ow meter is required. A routine lter cleaning schedule should
be established. The system should be shut down if abnormal noises occur or if unusual differential pressures across the
meter are encountered.
High Temperature Start Up: For uids above 82°C (150°F) based on 21°C (70°F) ambient, a special procedure is required
to prevent thermal shock and permanent damage to the ow meter. The warm up time is determined by the equation
below:
TIME (minutes) = connector size (inches) x (operating temperature (°F)-125)
10
— OR —
TIME (minutes) = connector size (inches) x (operating temperature (°C)-52)
10
Valves (#1) and (#2) must be closed. Open the bypass valve (#3) in gradual steps until the bypass piping is stabilized at
operating temperature. Open valve (#1) slightly and allow the temperature to stabilize around the ow meter. Valve (#1)
can then be opened completely.
Open valve (#2) slightly. The ow meter may make unusual noises or bind at this point. Leave the valve at this setting
until normal meter operation occurs, at which point valve (#2) can be gradually opened all the way. Slowly close the
bypass valve (#3).

Quick Start - No adjustments to factory settings
Your Max Flow Meter is connected to your process automation electronics via a 5-pin M12 Turck connector if an industrial
transmitter or via a 5-pin connector within a hazardous location housing with a 1/2 inch conduit connection. Please refer
to the EXInstall Sheet for proper installation of the wiring to the hazardous location housing.
Wire the 5-pin Turck cable to your process automation equipment in accordance with the diagrams below depending
upon which transmitter type you purchased. Then connect the Turck cable to the Turck tting on the Max Flow Meter.
Set your ouput reading on your process automation electronics to match the calibration sheet supplied with your ow
meter.
You are ready to measure your liquid ow application.
Start-up Instructions - Adjustments to Factory Settings Required
If you need to make adjustments to your Max Flow Meter prior to use, you will need to purchase and use the Max
Machinery Interface Software Kit (SFT-KIT-001). This will allow you to change the ow meter output signal frequency or
analog range to meet your application equipment needs.
To access the port on the circuit board, unscrew the transmitter lid by hand. The transmitter lid has four thread paths.
When reinstalling the lid, the cable may be misaligned. To realign the cable, remove the lid and rotate up to 180° and
retighten using an alternate starting point. Tighten to compress the O-ring seal.
Max Flow Meters do not come with a visual interface, they must be connected to an electronic display, PLC/DAC/counter
card or other process automation electronics to collect the data and display a visual reading.
You must determine if your process automation electronics have the capability to accept the high frequency output
of the Max Flow Meter. If your system cannot accept the data at the pre-set frequency, then use the Max Machinery
Interface Software Kit to adjust the frequency output to a lower setting that matches your system.
Refer to the Max Machinery Interface Software Kit Manual for instructions on how to change the ow meter output signal
frequency or analog range to meet your application’s equipment needs.

Applies only to transmitters with 5-pin, M12 style connectors. For hazardous location transmitters with 1/2 inch conduit
connections, please refer to the EXInstall sheet.
A current sinking device uses the transmitter’s transistor output to act as a
switch. Positive DC voltage must be applied to the transmitter's output pin (#2).
When the pulse output is triggered, this voltage is grounded to zero volts by the
transmitter. Warning: Use a 5k ohm resistor to limit current if your system does
not have other means to limit current into the transmitter.
