Installation Instructions

 

Installation Requirements

Piping condition
The installation of the Liquid Vortex Flowmeter requires specific straight pipe sections both upstream and downstream. The standard configurations are as follows (D denotes 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 must be mounted on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream to meet operational standards.
2.
The pipeline adjacent to the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on a pipe subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should match the sensor diameter as closely as possible. If an exact match isn't feasible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Avoid areas with strong electromagnetic interference, restricted space, or where maintenance access is difficult..
5.
Horizontal pipeline installations are most common for flow sensors. For gas flow measurements containing minor liquid amounts, position the sensor at a higher point in the pipeline. For liquid flow measurements containing minor gas amounts, position the sensor at a lower point in the pipeline.
6.
For vertical pipeline installations, when measuring gas flow, sensors can be placed on vertical pipelines without flow direction restrictions. If the gas contains a small amount of liquid, ensure the flow is from bottom to top. For liquid flow, the flow should also be from bottom to top to prevent additional weight on the probe.
7.
Side-mounted sensor installations on horizontal pipelines can be used for any fluid type but are particularly advantageous for measuring superheated steam, saturated steam, and low-temperature liquids. This positioning minimizes temperature effects on the amplifier.
8.
Inverted sensor installations on horizontal pipelines are not generally recommended for general gas or superheated steam measurements. They are suitable for measuring saturated steam and high-temperature liquids or in cases where pipelines require frequent cleaning.
9.
When installing sensors on pipelines with insulation layers, particularly for high-temperature steam measurements, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points: To meet measurement requirements, position the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream of the sensor.

Our Advantages

 

Features:

1. The structure is simple yet robust, featuring no moving parts. This ensures high reliability and long-term durability.The operation is highly dependable, built to perform seamlessly in various conditions.

1. Installation is straightforward and maintenance is exceptionally convenient, making it user-friendly.

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

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

1. Wide measurement range, range down up to 1:50.

1. Low pressure loss, low operating costs, and significant energy-saving benefits make it a cost-effective solution. Within a certain range of Reynolds numbers, the output signal frequency remains unaffected by changes in the fluid's physical properties and composition. The meter coefficient is only 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.
