4-1 General
Model 1305 flowmeters require little maintenance except routine cleaning.
It is necessary to remove the flowmeter from the line for tube and float
cleaning. The tube and float may be cleaned with a soft absorbent swab.
To disassemble the flowmeter proceed as follows:
a. Remove the front and rear window shields.
b. Remove four (4) screws connecting the bottom end fitting to the side
plate.
c. Carefully pull the end fitting and tube away from the side plates and top
fitting. DO NOT cock the tube when removing it from the top fitting.
d. Remove the polycarbonate sleeve surrounding the flow tube.
e. Remove the float from the tube.
Do not allow the float to fall out of the metering tube. A damaged
float will affect the accuracy of the meter. Be careful not to break the
tube by pulling on it at an extreme angle or applying excessive force.
f. Using a suitable solvent, carefully swab and flush the inside of the
metering tube. Clean the float and blow dry all parts thoroughly.
