Installation Instructions

 

Installation Requirements

Piping Condition
The installation of the vortex flowmeter requires a certain length of straight pipe both before and after the device. Here are the common scenarios (D represents the pipe diameter):

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 pipe that is horizontal, vertical, or inclined (with the liquid moving from bottom to top) and matches the sensor's diameter. Ensure a length of straight pipe both upstream (15-20D) and downstream (5-10D) of the sensor.
2.
The pipe near the liquid sensor must be completely filled with the liquid being measured.
3.
Do not install the sensor on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If not possible, opt for a slightly larger diameter pipe with an error ≤3%, not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow containing a small amount of liquid, position the sensor at a higher point in the pipeline. For liquid flow containing a small amount of gas, install the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation: For gas flow, install the sensor without flow direction restrictions. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flow, ensure the flow is from bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines: Sensors can be side-mounted for any fluid, especially suitable for measuring superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred if conditions allow, as it minimizes temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. Not suitable for general gases or superheated steam but can measure saturated steam and high-temperature liquids, or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers and high-temperature steam measurement, ensure the insulation does not exceed one-third of the bracket height.
10.
Pressure and temperature measurement points should be selected based on requirements. The pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream of the sensor.

Our Advantages

 

Key Features:

1. The structure is elegantly simple yet incredibly robust, featuring no moving parts for superior reliability and long-term performance.Operation remains consistently dependable over extended periods.

1. Ease of installation combined with very convenient maintenance.

1. The detection sensor remains isolated from the measured medium, assuring stable performance and an extended lifespan.

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

1. Offers a wide measurement range,spanning from 1:50.

1. Exhibits low pressure loss and operational costs, delivering significant energy-saving benefits. Within a specified range of Reynolds numbers, the signal frequency output remains unaffected by changes in the fluid's physical properties and composition. The meter coefficient depends solely on the shape and size of the vortex shedding body, rendering compensation unnecessary for fluid volume flow measurements.Typically, recalibration of the meter coefficient is unnecessary even when components are changed.
