Badger Meter 1100 - Manual (Page 5)

Installation
All Badger Meter Model 1100 turbine meters use stainless steel and tungsten carbide construction materials . Make sure the
operating fluid is compatible with these materials . Incompatible fluids can cause deterioration of internal components and
cause a reduction in meter accuracy .
The measured liquid should be free of any large particles that may inhibit rotation of the turbine blades . If particles are
present, install a mesh strainer upstream before operating the flow meter . See Table 1 for strainer recommendations .

Table 1: Strainer mesh installation details
The preferred plumbing setup is one containing a bypass line (see Figure 3 ) that allows meter inspection and repair without
interrupting flow . If a bypass line is not used, it is important that all control valves be located downstream of
the flow meter (see Figure 4 ) .
STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSES DAMAGE.
ATTENTION
DES DOMMAGES PEUVENT ÊTRE PROVOQUÉS EN FRAPPANT UN MÈTRE VIDE AVEC UN JET D’ÉCOULEMENT DE VITESSE
ÉLEVÉE.
This is true with any restriction in the flow line that may cause the liquid to flash . If necessary, install air eliminators to ensure
that the meter is not incorrectly measuring entrained air or gas .
Badger Meter recommends installation of a minimum length, equal to ten (10) pipe diameters of straight pipe on the
upstream side and five (5) diameters on the downstream side of the flow meter . Otherwise, meter accuracy may be affected .
Piping should be the same size as the meter bore or threaded port size .
Severe pulsation and mechanical vibration affect accuracy and shorten the life of the meter . If this condition is present,
consider using a flow meter possessing superior resistance to pulsation and vibration like the Badger Meter QuicSert . Do not
locate the flow meter or connection cable close to electric motors, transformers, sparking devices, high voltage lines, or place
connecting cable in conduit with wires furnishing power for such devices . These devices can induce false signals in the flow
meter coil or cable, causing the meter to read inaccurately .
If problems arise with the flow meter, consult the
Troubleshooting Guide on page 11 . If further problems arise, consult
the factory .
If damaged replace the internal components of the turbine flow meter with a turbine meter repair kit available from
Badger Meter . For information pertaining to the repair kits, see Turbine Replacement on page 8 .
