METER LOCATION, ORIENTATION AND APPLICATIONS
The M1000 provides two amplifier mounting options: an integral or meter mount option and a junction box/remote option .

Temperature Ranges
TO PREVENT DAMAGE TO THE METER, STRICTLY OBSERVE THE AMPLIFIER’S AND DETECTOR’S MAXIMUM
TEMPERATURE RANGES.
• In regions with extremely high ambient temperatures, protect the detector .
• In cases where fluid temperature exceeds 212° F (100° C), use the remote version .
Amplifier Ambient temperature – 4…140° F (–20…60° C)
Detector Fluid temperature
PTFE / PFA – 40…302° F (– 40…150° C)
Hard rubber 32…176° F (0…80° C)
Remote Amplifier Outdoor Location
The amplifier can be installed and operated outdoors . However, it must be protected from the elements, as follows:
• The ambient environment/temperature rating for the unit is – 4…140° F (–20…60° C) .
• If an indoor location is within 150 feet (50 meters) of the detector, consider increasing the cable length and mounting the
amplifier indoors .
• At minimum, fabricate a roof or shield over and/or around the amplifier to protect the LCD display screen from direct
sunlight .
Pipelines and Fluid Flow
Take the following precautions during installation:
• Do not install the meter on pipes with extreme pipe vibrations . If pipes are vibrating, secure the piping with appropriate
pipe supports in front of and behind the meter . If vibrations cannot be restrained, mount the amplifier in a remote
location .
• Do not install the detector close to pipeline valves, fittings or impediments that can cause flow disturbances .
• For detectors with PTFE liners, do not install the detector on suction sides of pumps .
• Do not install the detector on outlet sides of piston or diaphragm pumps . Pulsating flow can affect meter performance .
• Avoid installing the detector near equipment that produces electrical interference such as electric motors, transformers,
variable frequency, and power cables .
• Verify that both ends of the signal cables are securely fastened .
