Installation Instructions

 

Installation Requirements

Piping Condition
The installation of the vortex flowmeter requires specific straight pipe sections before and after the sensor. The common configurations are as follows (D represents the diameter of the pipe):

Piping condition	upstream	Downstream
Concentric shrinkage pipe full open gate valve	15D	5D
∠90° square elbow	20D	5D
Same plane 2∠90°elbow	25D	5D
Semi-open gate valve regulating valve	50D	5D
Different plane 2∠90°elbow	40D	5D
With rectifier tube bundle	12D	5D

 

1.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a specified length of straight pipe is present both upstream and downstream, requiring 15-20D for the front section and 5-10D for the rear section.
2.
The pipe near the liquid sensor should always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
Ensure the inner diameter of the straight pipe section is as consistent as possible with the sensor diameter. If consistency isn't possible, use a slightly larger diameter pipe, with an error margin of ≤3% and not exceeding 5mm. Avoid installation in areas with strong electromagnetic interference, limited space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurement, if the gas contains minor liquid quantities, place the sensor at a higher point in the pipeline. Conversely, for liquid flow measurement with minor gas presence, install the sensor at a lower point.
6.
Sensor installation in vertical pipelines: For gas flow measurement, install the sensor on a vertical pipeline without restricting flow direction. If the gas contains minor liquid quantities, the gas flow should be bottom to top. For liquid flow, ensure the flow is from bottom to top to prevent additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines: Suitable for all fluids, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible, as it reduces the temperature impact on the amplifier.
8.
Inverted installation of sensors 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, or when frequent pipeline cleaning is needed.
9.
When installing sensors on pipelines with insulation layers, ensure the insulation layer does not exceed one-third of the bracket height, especially for high-temperature steam.
10.
Selecting pressure and temperature measurement points: Depending on measurement needs, position the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.

Our Advantages

 

Features:

1. The structure of the Low Pressure Loss Anti Vibration Flowmeter for Liquid and Gas is simple, yet robust. With no moving parts, it ensures high reliability and long-term performance.Operation is highly dependable, making it a trusted choice for various applications.

1. Installation is straightforward, and maintenance is exceptionally convenient, reducing downtime and labor.

1. The detection sensor does not directly contact the measured medium, ensuring stable performance and extending its lifespan.

1. The output is a pulse signal proportional to the flow rate, ensuring no zero drift and maintaining high accuracy.

1. Wide measurement range, offering flexibility for different measurement needs,with the range goingup to 1:50.

1. Low pressure loss, leading to reduced operating costs and significant energy-saving benefits. Within a certain range of Reynolds numbers, the output signal frequency remains unaffected by changes in the physical properties and composition of the fluid.The meter coefficient is solely related to the shape and size of the vortex shedding body, eliminating the need for compensation when measuring fluid volume flow. Generally, recalibration of the meter coefficient is not required after changing components.
