Installation
All Pembina Controls Inc. Meter Model BP1100 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.

The preferred plumbing setup is one containing a bypass line (see Figure 3 on page 6) 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 on page 6).
STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSE DAMAGE.

ÉLEVÉE.
Any restriction in the flow line may cause the liquid to flash. If necessary, install air eliminators so that the meter is not
incorrectly measuring entrained air or gas.
Pembina Controls Inc. recommends installation of a minimum straight pipe length, equal to ten (10) pipe diameters 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 Pembina Controls Inc. QuikSert.
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 12. If further problems arise, consult
the factory.
Replace damaged internal components of the turbine flow meter with a turbine meter repair kit available from Pembina
Controls Inc. See Turbine Replacement on page 8.
