Procedure for Cleaning a Turbine Meter after Water Calibration and/or Service
OTEE:
N
When cleaning flow meters, keep the body, sleeve and pickoff together . Sleeve is fitted to body and pickoff has a
protruding pin . Replacement pickoffs are supplied with a nut and have no protruding pin .
1 . Remove the meter from the line and let all excess water drip out .
2 . Fill the meter with alcohol (at least 50% Isopropyl, Ethyl or Methyl) and let it stand for 5 minutes .
3 . Discard the alcohol and let the meter dry for 2 minutes .
4 . Fill the meter with MIL-C-7024 Type 2 calibration fluid (or similar solvent) and let it stand for 1 minute .
5 . Discard the calibration fluid and flush the meter with an approved fluorocarbon solvent, such as Isotron .

If this procedure is not possible, the turbine meter should always remain filled with water when not in use, to prevent
internal wetted parts from being exposed to air .

Order parts by name and basic number shown, followed by flow meter
size designation . For example, order a bearing for a CLFF6 flow meter
as bearing #1400-63 . Flow meter serial number must be provided when
ordering parts .
