FLOW MEDIUM Please note that PWE Flow Meters
are designed to work only with liquids. Never try to measure flow rates of dry
gas. |
| CALIBRATIONS Performed at standard conditions
[14.7 psia (101.4 kPa) and 70°F (21.1°C)] unless otherwise requested or
stated. |
| VISCOSITY Calibrated to 1 cSt (water). Meters
with display can be used for fluids up to 50 cSt with field calibration (maximum
flow range may be affected). |
| ENVIRONMENTAL (PER IEC 664) Installation Level
II; Pollution Degree II. |
| FLOW ACCURACY (INCLUDING LINEARITY) ±1% of
FS |
| REPEATABILITY ±0.25% of full
scale. |
| FLUID TEMPERATURE MEASURMENT RANGE* -10 to 70
°C |
| TEMPERATURE ACCURACY (INCLUDING LINEARITY)*
±0.5 °C |
| FLOW RESPONSE TIME approximately 1 seconds
(above 10% of full scale flow), approximately 2 seconds (below 10% of full scale
flow) |
| MAXIMUM PRESSURE 10 bar (150
psi) |
| MAXIMUM PRESSURE DROP 1.4 bar (20 psi) at
132.5 L/min flow. See Table IV for pressure drops associated with various models
and flow rates. |
| FLUID AND AMBIENT TEMPERATURE 14°F to 160°F
(-10°C to 70°C) |
