Intelligent Vortex flowmeter installation requirements
Intelligent Vortex flowmeter, band temperature and pressure compensation, flow measurement of steam, convenient and easy installation, the following are some of its attention to points on the installation.
A reasonable choice of installation site and environment
Avoid strong electrical equipment, high-frequency equipment, strong power switching equipment; avoid the impact of high temperature heat and radiation sources, avoid intense vibration place and highly corrosive environment, taking into account easy installation and maintenance.
Second, there must be sufficient upstream and downstream straight pipe
If the sensor is installed upstream of the point on the same plane with two 90. Elbow, then: straight pipe upstream ≥25D, downstream straight pipe ≥5D.
If the sensor is installed upstream of the point on a different plane with two 90. Elbow, then: straight pipe upstream ≥40D, downstream straight pipe ≥5D.
Regulating valve should be installed in a location other than the downstream 5D sensor, if the sensor must be installed upstream of the upstream sensor straight pipe should be not less than 50D, downstream should be not less than 5D.
Third, the installation point downstream piping should be concentric with the sensor, coaxial deviation shall not be less than half the diameter.
Fourth, the pipeline to take measures to reduce vibration
Sensors should avoid mounted on vibration strong pipeline, particularly lateral vibrations. If forced to install, damping measures must be taken, at the downstream 2D ??sensor is provided on the pipe fastening means, respectively, and add anti-vibration pad.
V. Installation in horizontal pipe flow sensor is the most common installation method.
When measuring gas flow, if measured gas contains a small amount of liquid, the sensor should be installed in the pipeline at the higher.
When the measurement of liquid flow, if the measured liquid containing a small amount of gas, the sensor should be installed at the lower line.
Sixth, the sensor is installed in a vertical pipe
When measuring gas flow, the sensor can be installed in a vertical pipe, the flow limitation. If the measured gas containing a small amount of liquid, gas flow by bottom up.
When the measurement of liquid flow, liquid flow should be bottom up, so does the extra weight of the liquid attached to the probe.
So, whether it is choice or pipe installation environment, there are certain requirements that only meet the installation requirements to ensure the safety of the meter in normal use.
