The National Electronics Manufacturer's Association (NEMA) 6P enclosures are constructed for indoor or outdoor use . The 6P
enclosures provide protection against access to hazardous parts . They also provide a degree of protection against ingress of
solid foreign objects and water (hose directed water and the entry of water during prolonged submersion at a limited depth)
which provide an additional level of protection against corrosion and that are not damaged by the external formation of ice
on the enclosure .
Temperature Ranges
TO PREVENT DAMAGE TO THE METER, STRICTLY OBSERVE THE TRANSMITTER’S AND SENSOR’S MAXIMUM
TEMPERATURE RANGES.
• To prevent damage to the meter, strictly observe the transmitter and sensor temperature ranges .
• In regions with extremely high ambient temperatures, protect the sensor from extreme temperatures .
• In cases where fluid temperature exceeds 212° F (100° C), use the remote mount version .
Transmitter
Ambient temperature
–4…140° F (–20…60° C)
Sensor
Fluid temperature
PTFE/PFA
–40…302° F (–40…150° C)
Hard rubber
32…176° F (0…80° C)
Soft rubber
32…176° F (0…80° C)
Protection Class
To fulfill requirements of the protection class, follow these guidelines:
• Make sure body seals are undamaged and in proper condition .
• Firmly screw in all the body screws .
• Outer diameters of the wiring cables must correspond to cable inlets (for M20 Ø 5 . . . .10 mm) . In cases where cable inlet is
not used, put in a dummy plug .
• Tighten cable inlets .
• If possible, lead cable away downwards to prevent humidity from entering cable inlet .
The standard option is protection class IP 67 . If you require a higher protection class, use the remote mount version . NEMA
6P / IP 68 is an option for the sensor with the remote mount version .
Pipelines and Fluid Flow
Take the following precautions during installation:
• Do not install the meter on pipes with extreme vibrations . If pipes are vibrating, secure the piping with appropriate pipe
supports in front of and behind the meter . If vibrations cannot be restrained, use the remote mount option .
• Do not install the sensor close to pipeline valves, fittings or impediments that can cause flow disturbances .
• For sensors with PTFE liners, do not install the sensor on suction sides of pumps .
• Do not install the sensor on outlet sides of piston or diaphragm pumps . Pulsating flow can affect meter performance .
• Avoid installing the sensor near equipment that produces electrical interference such as electric motors, transformers,
variable frequency or power cables .
• Make sure both ends of the signal cables are securely fastened .
• Place power cables and signal cables in separate conduits .
• Place the meter where there is enough access for installation and maintenance tasks .
• Install the meter with the forward flow label on the meter body matching the pipeline flow .
