Installation Instructions

 

Installation Requirements

Piping condition
The installation of the vortex flowmeter requires specific straight pipe sections before and after the sensor to ensure accuracy. The common recommendations are as follows (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.
Install the sensor on a pipe that is horizontal, vertical, or inclined (with the 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 of the sensor.
2.
Ensure that the pipe near the liquid sensor is fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with strong mechanical vibrations to maintain measurement stability.
4.
Maintain consistency in the inner diameter of the straight pipe section and the sensor. If matching is not possible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common. When measuring gas flow containing a small amount of liquid, install 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.
6.
Vertical pipeline sensor installation: For gas flow measurement, install on a vertical pipeline with no flow direction restrictions. If 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 avoid additional weight on the probe.
7.
Side installation on horizontal pipelines is suitable for measuring superheated steam, saturated steam, and low-temperature liquids. It is preferred when conditions allow, as it reduces temperature impact on the amplifier.
8.
Inverted installation 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 in situations requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: For precise results, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.

COMPANY AND FACTORY PICTURE:
 

Our Advantages

 

Features:

1. The structure is ingeniously simple yet exceptionally robust, boasting no moving parts, which ensures high reliability and a long operational life.Operation is remarkably dependable.

1. Installation is seamless and maintenance is extremely convenient.

1. The detection sensor avoids direct contact with the measured medium, guaranteeing stable performance and an extended lifespan.

1. The output is a pulse signal directly proportional to the flow rate, featuring no zero drift and outstanding accuracy.

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

1. Experience minimal pressure loss, low operating costs, and significant energy savings. Within a certain range of Reynolds numbers, the output signal frequency remains unaffected by variations in the physical properties and composition of the fluid. The meter coefficient is exclusively linked 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 unnecessary after component changes.
