LSZ dual-rotor flowmeter
is my own research and development company,
the latest version of volumetric flow juice.
In the pipeline for liquid flow measurement
and control of precision instruments. Measurement
with high accuracy, smooth operation, no pulse,
low noise, long life and the viscosity change
adaptation and so on. Therefore, in the oil,
chemical, metallurgical, power, shipping,
transport, port, mines, thermoelectric, food
and other departments widely used. Particularly
applicable to crude oil, condensate oil high,
high moisture content of crude oil, oil products,
food and chemical solution business transactions
measurement and automation project management
control measures. Flowmeter can be directing,
code directly reading. Pulse and photoelectric
converters with output pulse (current) signals
for display instrument and juice processing
machine operator, so that the liquid flow
in pipes can be remote centralized control. |
Dual-rotor
flowmeter measurement Room, and a
spiral shell and rotor composed of
upper and lower plate, and they formed
a number of known size of the cavity
as a flowmeter measurement units.
Flowmeter rotor on their import and
export of the tiny pressure promote
rotation, and will continue to import
liquid metering to the cavity exports
(see figure 2), the rotor will rotate
frequency coupling and sealing drive
system Transfer to count bodies, the
direct instructions of the total flow
through the liquid flowmeters. |
