Glass tube rotameter gas flow meter
Product Description
The series of glass rotor flowmeter is an intergrated product by coneshaped glass tube,Float, flanges. The
installation is easy and the flowmeter is adjustable, the flowmeter is used in ranges such as
semi-conductor chemicals ect.
Large range application
It is usually used for low pressure, high temperature sheer liquid or gases without suspending particles and
has been widely employed in various industries e.e petroleum,chemicals, electronics,environmental
protection, power supply and medicine.

The installation of the equipment
Enough room should be available around the equipment for easy maintenance.
For calibration, repair, changing and cleaning of the equipment, by-pass should be fitted along the equipment. (see below picture for detail)
The pipeline should be cleaned for the first time installation.
The pipeline should be immovable before installation of the equipment to prevent damage.
One way check valve should be installed at downstream of the equipment to prevent equipment damage from countercurrent, especially water v-cone.
Filter should be installed at upstream of the equipment when application content particles and dirt to prevent blocking of the pipeline.
Suitable buffer or amount setting device should be installed at upstream of the equipment when the application is in pulsating flow to prevent shaking of the float.
The flow meter should be installed vertically.
Valve should be fitted at upstream and flow control valve should be installed at downstream at 5~10 times distance of the bore size.
