Installation Requirements
Piping Condition
For optimal performance of the Low Pressure Loss Vortex Flowmeter, ensure a specific length of straight piping both before and after the installation point (D represents the pipe diameter). The typical guidelines are as follows:
1.
Install the sensor on a horizontal, vertical, or inclined pipe (with liquid flowing upwards) that matches the sensor's diameter. Ensure there is a straight pipe section of 15-20D upstream and 5-10D downstream.
2.
Ensure the pipe near the liquid sensor is completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should ideally match the sensor diameter. If not, use a slightly larger diameter pipe with a deviation of ≤3%, not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common. For gas flow containing a small amount of liquid, install the sensor at a higher pipeline point. For liquid flow containing a small amount of gas, install it at a lower pipeline point.
6.
For vertical pipeline installation, there are no restrictions on flow direction when measuring gas. If the gas contains some liquid, ensure bottom-up flow. For liquid flow, also ensure bottom-up flow to avoid additional weight on the probe.
7.
Sensors can be side-mounted on horizontal pipelines, ideal for superheated steam, saturated steam, and low-temperature liquids. Side mounting reduces temperature impacts on the amplifier when conditions allow.
8.
Inverted installation on horizontal pipelines is generally not recommended. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, particularly where frequent pipeline cleaning is required.
9.
For high-temperature steam applications, the insulation layer on the pipeline should not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: When required, position the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream of the sensor.
