Installation Instructions

 

Installation Requirements

Piping condition
The installation of vortex flowmeters requires specific straight pipe sections before and after the device. The common scenarios (D represents the pipe diameter) include:

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 mounted on a horizontal, vertical, or inclined pipe (with liquid flowing upwards). This pipe should match the sensor's diameter. Ensure there are adequate straight pipe lengths both upstream (15-20D) and downstream (5-10D) of the sensor.
2.
The pipe adjacent to the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe sections should closely match the sensor diameter. If not identical, opt for a slightly larger diameter, with a permissible error of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, limited space, or where maintenance is cumbersome..
5.
Horizontal pipeline installation is the most prevalent method. When measuring gas flow containing minimal liquid, install the sensor at an elevated point. For liquid flow with minor gas content, place the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation. For gas flow measurements, the sensor can be installed on a vertical pipe regardless of flow direction. If the gas contains a small amount of liquid, the flow should be bottom-to-top. For liquid measurements, the flow should also be bottom-to-top to prevent additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines is feasible. This approach is especially valuable when measuring superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when conditions permit, as it reduces temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally not recommended. It is unsuitable for general gas or superheated steam measurements but can be applied for saturated steam and high-temperature liquids or when frequent pipeline cleaning is necessary.
9.
When installing sensors on pipelines with insulation layers and measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points. If measurements near the sensor are required, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.

Our Advantages

 

Features:

1. The structure is elegantly simple yet incredibly robust, boasting no moving parts for heightened reliability and extended lifespan.Operation is highly dependable, ensuring consistent performance over time.

1. Installation is straightforward, while maintenance is remarkably convenient, saving you time and effort.

1. The detection sensor remains isolated from the measured medium, guaranteeing stable performance and a prolonged lifespan.

1. The output provides a pulse signal proportionate to the flow rate, maintaining high accuracy without zero drift.

1. The device offers a wide measurement range,range down up to 1:50.

1. Enjoy low pressure loss and reduced operating costs, resulting in significant energy-saving benefits. The output signal frequency remains unaffected by changes in the fluid's physical properties and composition within a certain range of Reynolds numbers. The meter coefficient is solely influenced by the shape and size of the vortex shedding body, negating the need for compensation when measuring fluid volume flow. Typically,recalibration of the meter coefficient is unnecessary even after component changes.
