Installation Instructions

 

Installation Requirements

Piping condition
The installation of vortex flowmeters requires specific straight pipe sections both before and after the device. The common guidelines are as follows (where D represents the pipe's 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 must be installed on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) that matches the sensor's diameter. Ensure there is a straight pipe section both upstream and downstream of the sensor: 15-20D in front and 5-10D behind.
2.
The pipe close to the liquid sensor should be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that are subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor's diameter. If a difference exists, opt for a slightly larger pipe with an error margin of ≤3% and no more than 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, confined spaces, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most prevalent method for flow sensors. When measuring gas flow that contains a small amount of liquid, place the sensor at a higher point in the pipeline. Conversely, when measuring liquid flow containing a small amount of gas, place the sensor at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines. When measuring gas flow, the sensor can be installed on a vertical pipeline without flow direction restrictions. For gas containing some liquid, ensure the flow is from bottom to top. For liquid flow, position the sensor so that the flow is from bottom to top to prevent additional burden on the probe.
7.
Side-mounted sensors on horizontal pipelines are versatile, suitable for measuring superheated steam, saturated steam, and low-temperature liquids. If possible, side mounting is preferred to minimize the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally discouraged and not suitable for measuring typical gases or superheated steam. It can be employed for saturated steam and high-temperature liquids or when frequent pipeline cleaning is required.
9.
When installing sensors on pipelines with insulation layers, for high-temperature steam measurements, the insulation layer should not surpass one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: To meet specific measurement needs, locate the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream of the sensor.

Our Advantages

 

Outstanding Features:

1. Boasting a simple yet robust structure, this flowmeter features no moving parts, ensuring high reliability and extended longevity.Dependable and consistent operation.

1. Designed for straightforward installation and hassle-free maintenance.

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

1. Delivers a pulse signal proportional to the flow rate, exhibiting no zero drift and offering unparalleled accuracy.

1. Extensive measurement range,handling flow ratesup to 1:50.

1. Minimal pressure loss, reduced operating costs, and enhanced energy efficiency. Within a specific range of Reynolds numbers, the output signal's frequency remains unaffected by changes in the fluid's physical properties and composition. The meter coefficient is solely determined by the vortex shedding body's shape and size, eliminating the need for compensation when measuring fluid volume flow. Typically,recalibration of the meter coefficient is unnecessary even after component changes.
