DESCRIPTION
The Brooks® Model 1305 glass tube flowmeters provide
a low cost means of flow rate indication and alarm
signaling. They are designed for applications where the
metering accuracy requirements are not severe. These
meters are ideal for purge type service, seal oil systems,
bearing lubrication and cooling water indication. Model
1305 is available with vertical inlets and outlets and
standard materials of construction only. A general purpose
alarm, with flow contacts over the entire flow range, is
optional.
