SUMMARY
UQ960 series Vortex flowmeter is one of the vibration flowmeters. It based on "Karman"
principle and has simple configuration, and install conveniently. It can measure for
iquid, gas, and steam. U960 widely used in petroleum, chemicals, Iron, steel,
metallurgy, paper, food, urban drainage and other industries. We use new technology
for Battery function and reduce your engineering design headaches. It's a cost-effective
and high stability flowmeter.
No moving parts
FEATURE

Low power: more than one year
5 points non-linear function
High stability for Automatic cheek & adjustments
Low pressure loss
Wide application for steam, gas liquid
PRINCIPLE
The periodic shedding of eddies occurs first from one side and then from
the other side of a bluff body (Vortex-shedding body) installed
perpendicular to the pipe axis. Vortex shedding generates a so-called
"Karman Vortex Street" with altemating pressure conditions whose
frequency "f" is proportional to the flow velocity "V". The non-dimentional
Strouhal number "S" (primary head constant) describes the relationship
between Vortex shedding frequency F (in Hz) width b of the body, and
mean flow velocity v (in m/s)
F=S+v/b
The flexural vibration of the Vortex-shedding body is picked up in the
primary head via sensors and analysed in the signal converter. In the case
of the gaseous, flowing media, the vibration frequency ranges between 10
and 7000 Hz.
