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.
CAUTION
Failure to drain the flowmeter when isolated in a bypass loop may
result in tube breakage caused by thermal expansion of the process
liquid.
CAUTION
Horizontal outlet connection is provided on Model 1307 flowmeters
supplied with an alarm. For those flowmeters supplied with an alarm, the
outlet end fitting may be rotated in 90° increments.
