Vortex Flow Meter To Measure Steam With External Temperature and Pressure Compensation
Vortex flowmeters are often used to measure
steam flow. When measuring steam mass flow, we will be equipped with industrial temperature sensor (RTD), pressure transmitter and AJ series flow totalizer.
When these instruments are in use, temperature value from RTD，PT100, pressure signal
(4-20mA) and vortex volume Flow signal (4-20mA or pulse) will input into the
flow totalizer, the flow totalizer will calculate the steam mass flow value. It means we need pressure sensor ,pt100 and flow computer to realise external temperature and pressure compensation.
Saturates steam and Over heated steam Flow measurement
The STLU series of high temperature vortex
flowmeters can measure temperatures up to 350 degrees Celsius. Therefore,
vortex flowmeters can measure both saturated steam flow and high temperature
superheated steam flow.
Steam Flow totalizer information
From the AJ Flow totalizer , we can read
the steam temperature ,pressure information as well, not only instant mass flow
and total mass flow. Below is the AJ Flow totalizer display screen.
Overview of Vortex flow meter
When selecting a vortex sensor of the
appropriate diameter, users need to provide the operation temperature, pressure
and flow range to the silver automation instruments, and the sales engineer
will select the appropriate vortex flowmeter sensor size based on these
The steam vortex flowmeter uses a
piezoelectric stress sensor with high performance reliability and can operate
in a fluid temperature range of -20 ° C to +350 ° C. The working pressure loss
is small, the measuring range is wide, and the measurement range of saturated
steam can reach 30 to 1, and the steam vortex flowmeter measurement technology
is mature. It has analog standard signal and digital pulse signal output, which
can be used with digital systems such as computers. It is a relatively advanced
and ideal measuring instrument. Widely used in superheated steam, saturated
steam, high temperature steam, etc.
