Calibration
Water (NIST Traceable Calibration)
Corrosion
Constructed of stainless steel and tungsten carbide� The
operator 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�
Pulsation and
Vibration
Severe pulsation and mechanical vibration will affect accuracy
and shorten the life of the meter�
