4-1 General
Model 1358 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. Loosen the seal spindle or jack screw by turning it counterclockwise
with a 5/32" hex wrench.
c. The tube may now be canted out of the meter housing.
d. Remove the polycarbonate sleeve surrounding the flow tube.
e. Remove the float and float stops from the tube.
f. Using a suitable solvent, carefully swab and flush the inside of the
metering tube. Clean the float and blow dry all parts thoroughly.
g. The packing seats may now be removed. It is recommended that the
packing be replaced each time the meter is serviced.
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.
