INSTALLATION

PRESSURE IN EXCESS OF ALLOWABLE RATING MAY CAUSE THE HOUSING TO BURST AND CAUSE SERIOUS PERSONAL

INJURY.
Check the internals of the flow meter for any foreign material Ensure the turbine rotor spins freely prior to installation Also,

check fluid lines and remove any debris found
Install the flow meter with the flow arrow, etched on the exterior of the meter body, pointing in the direction of fluid flow

Though the meter is designed to function in any position it is recommended, where possible, to install horizontally with the

conduit adapter facing upward Thread a magnetic pickup into the conduit adapter completely finger tight without forcing

Secure with a lock nut if supplied Install conduit or other fittings suitable for the installation area onto the conduit adapter

hub on the flow meter
All Blancett Model 1200 turbine meters use stainless steel construction materials The user must ensure that 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: Filtration recommendations

The preferred plumbing setup is one containing a bypass line (

Figure 2

) that allows meter inspection and repair without

interrupting flow If a bypass line is not utilized, it is important that all control valves be located downstream of the flow

meter (

Figure 3

)

STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSES DAMAGE.
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
Blancett 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
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
