Installation Instructions

 

Installation Requirements

Piping Condition
The installation of a vortex flowmeter requires specific straight pipe sections both upstream and downstream. The common configurations are as follows (D represents 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.
Install the sensor on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure adequate straight pipe lengths: 15-20D upstream and 5-10D downstream.
2.
Ensure the pipe near the liquid sensor is fully filled with the liquid to be measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If not, use a slightly larger pipe, ensuring an error of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is difficult. Installation requirements.
5.
Horizontal pipeline installation is most common. For gas flow with small liquid content, install the sensor at a higher pipeline point. For liquid flow with small gas content, install at a lower point.
6.
Vertical pipeline installation involves no flow direction restriction for gas flow. For gas with small liquid content, ensure flow direction is from bottom to top. For liquid flow, flow should be from bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is possible for any fluid, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting minimizes 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 where frequent pipeline cleaning is required.
9.
For pipelines with insulation layers measuring high-temperature steam, the insulation should not exceed one-third the height of the bracket.
10.
When measuring pressure and temperature near the sensor, place pressure measurement points 3-5D downstream and temperature measurement points 6-8D downstream.

COMPANY AND FACTORY PICTURE:
 

Our Advantages

 

Outstanding Features:

1. Designed with simplicity and robustness in mind, our flowmeter boasts no moving parts, ensuring high reliability and enduring performance.It operates with remarkable dependability, offering peace of mind.

1. Installation is a breeze, and maintenance is exceptionally convenient.

1. Our detection sensor never comes into 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, ensuring no zero drift and impeccable accuracy.

1. It offers a broad measurement range, with a turndown ratio up to an impressive 1:50.0.

1. Featuring low pressure loss, our flowmeter significantly reduces operating costs while delivering substantial energy-saving benefits. 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 remains constant, determined solely by the shape and size of the vortex shedding body, thereby eliminating the need for compensation when measuring fluid volume flow. In most cases,recalibration of the meter coefficient is unnecessary even after component changes.
