JG-HLUG series with temperature and pressure compensation-in-one
flowmeter is mainly used for industrial pipe medium fluid flow
measurement, such as gas, liquid, vapor and other media. One type
vortex flowmeter is the pressure loss characteristics, scale range,
high precision in the measurement conditions are not nearly the
volume density of the fluid flow, pressure, temperature, viscosity
and other parameters. No moving mechanical parts, so high
reliability and little maintenance. Long-term stability of the
instrument parameters. This instrument uses piezoelectric stress
sensors, high reliability, can be -20~ +250operating temperature
range. With analog standard signal, but also digital pulse signal
output, easily supporting the use of computers and other digital
systems is a more advanced and ideal flow
VSF-one vortex flowmeter output pulse frequency signal from fluid
properties and composition changes, that instrument coefficient in
a certain Reynolds number range, and only with the bluff body shape
and size of the pipe and so on. But as the material balance and
energy flow in the measurement of mass flow to be detected, then
the flow meter should also monitor the volume of the output signal
flow and fluid density, fluid properties and composition of the
flow measurement or have a direct impact
Karman vortex flowmeter vortex principle is the basis for
Measurement of fluid flow in closed conduits new flow meter. Media
because of its good ability to adapt, without direct measurement of
temperature and pressure compensation can be steam, air, gas,
water, liquid volume flow conditions, with temperature and pressure
sensor measures the standard volume flow and mass flow conditions,
is to cut expenditure Flowmeter ideal alternative
To improve the high temperature vortex flowmeter and anti-vibration
performance, the company recently developed a HLUG improved vortex
flow sensors, because of its unique structure and selection of
materials so that the sensor at high temperature (350 ℃), high
vibration (& le ; 1g) use of harsh conditions
In practice, the maximum flow rate is often much lower than the
upper limit of the instrument, as the load changes, the minimum
flow rate and often lower than the lower limit of the instrument,
meters are not working in its optimum operating segment, in order
to solve this problem , commonly used in the measurement at the
reduced diameter to improve the measurement at the flow rate, and
smaller-diameter instrument to facilitate selection of the
measurement instrument, but this must be adjustable means between
adjustable tube and instrument over a length of straight pipe
section 15D to Rectifier, the processing, installation is not easy.
Our company has developed a vertical section of the shape of arc
rectifier LGZ adjustable, with a rectifier to improve the flow and
velocity distribution change multiple roles, its structure, small
size, process tube diameter of only 1 / 3, one made with the vortex
flowmeter Not only do not need to add another section of straight
pipe, you can also reduce the process tube straight pipe
requirements, installation is easy
For ease of use, battery-powered display-type vortex flowmeter of
local micro-power high-tech, using lithium uninterrupted power
supply can run more than one year, saving the cable and display
instruments for the procurement and installation costs, may show
the instantaneous Flow, cumulative flow. Temperature compensation
is also a body vortex flowmeter with a temperature sensor, can
measure the temperature of saturated steam and calculate the
pressure, which shows the mass flow of saturated steam. Temperature
and pressure compensation for a body with a temperature and
pressure sensors, gas flow measurement can be directly used to
measure the temperature and pressure of gas medium, which shows the
standard conditions of gas volume flow
