Configuration and Service Notes
- The PD7 capacity is the Brooks catalog value for water. Suitability or indicated flow for another fluid depends on that fluid and the actual operating temperature, pressure, density, and calibration data.
- Model 1510 scales may use linear reference graduations with an air or water calibration table, or a direct-reading tube decal. The installed tube markings and calibration record govern how an individual instrument is read.
- The metering tube can be removed without disconnecting the instrument; integral PTFE float stops retain the float during tube removal.
- Brooks lists its outlet check valve as unavailable when an optional needle valve is installed on the outlet. Because suffix G specifies an outlet valve, a check valve should not be asserted for this configuration.
