Badger Meter M-Series M1000 - Manual (Page 12)

AMPLIFIER MOUNTING CONFIGURATION OPTIONS
There are two configuration options for mounting the amplifier . There are many options to accommodate a variety of
meter-placement and environmental conditions .
Meter Mount Configuration
The meter mount configuration has the amplifier mounted directly on the detector . This compact, self-contained
configuration minimizes installation wiring .
Remote Mount Configuration
The remote mount configuration places the amplifier at a location away from the fluid flow and detector . This is necessary in
situations where process fluid temperature or the environment exceeds amplifier ratings .
The detector and amplifier are connected by wires, run through conduit, between junction boxes on the detector and the
amplifier . The distance between the detector junction box and amplifier junction box can be up to 150 feet (50 meters) . A
remote mounting bracket is supplied .
Submersible Option
If you are installing the meter in a vault, you should order the remote mount, submersible amplifier option . You must not
install the amplifier inside a vault . This will eliminate any potential problems resulting from humidity or temporary flooding in
the vault .
OTEE: N The National Electronics Manufacturer's Association (NEMA) 6P enclosures are constructed for indoor or outdoor use
to provide protection against access to hazardous parts; to 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); that provide an additional level of protection against corrosion and that will be undamaged by the external
formation of ice on the enclosure .
Protection Class
In order to fulfill requirements of the protection class, follow these guidelines:
• BODY SEALS NEED TO BE UNDAMAGED AND IN PROPER CONDITION.
• ALL OF THE BODY SCREWS NEED TO BE FIRMLY SCREWED.
• OUTER DIAMETERS OF THE USED WIRING CABLES MUST CORRESPOND TO CABLE INLETS (FOR M20 Ø 5....13 MM). IN
CASES WHERE CABLE INLET IS NOT USED, PUT ON A DUMMY PLUG.
• TIGHTEN CABLE INLETS.
• IF POSSIBLE, LEAD CABLE AWAY DOWNWARDS. HUMIDITY CANNOT GET INTO CABLE INLET.
• WE NORMALLY DELIVER THE METER IN ACCORDANCE WITH PROTECTION CLASS IP 67. IF YOU HOWEVER REQUIRE A
HIGHER PROTECTION CLASS, THE AMPLIFIER IS TO BE INSTALLED SEPARATELY FROM THE DETECTOR. IF REQUESTED,
WE CAN ALSO DELIVER THE DETECTOR IN IP 68.
