Installation Instructions

 

Installation Requirements

Piping condition
The installation of the vortex flowmeter mandates a specific straight pipe section both upstream and downstream. The typical configurations 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.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing bottom to top) matching the sensor's diameter. Ensure straight pipe sections: 15-20D upstream and 5-10D downstream.
2.
The pipe adjacent to the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If a match isn't possible, use a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Avoid strong electromagnetic interference, constrained spaces, or areas difficult to maintain..
5.
For horizontal pipeline installation, commonly used for flow sensors: when measuring gas flow with minor liquid content, position the sensor at a higher pipeline point; for liquid flow with minor gas content, position it at a lower point.
6.
Vertical pipeline sensor installation: for gas flow, without flow direction restriction. If gas contains liquid, flow should be bottom to top. For liquid flow, ensure it moves bottom to top to reduce probe weight.
7.
Side mounting on horizontal pipelines: applicable to any fluid measurement, especially superheated steam, saturated steam, and low-temperature liquids. Prefer side mounting to minimize amplifier temperature impact.
8.
Inverted horizontal pipeline sensor installation: generally discouraged, unsuitable for general gases or superheated steam. Suitable for saturated steam and high-temperature liquids, or for frequently cleaned pipelines.
9.
Sensors on insulated pipelines: for high-temperature steam, the insulation layer must not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: position pressure measurement 3-5D downstream of the sensor, and temperature measurement 6-8D downstream, based on specific measurement needs.

Our Advantages

 

Exceptional Features:

1. The structure is both simple and robust, featuring no moving parts, which enhances reliability and ensures long-term durability.Highly dependable operation is guaranteed for all applications.

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

1. The detection sensor does not come into direct contact with the measured medium, guaranteeing consistent performance and an extended lifespan.

1. The output delivers a pulse signal that is directly proportional to the flow rate, eliminating zero drift and offering high accuracy.

1. Featuring a wide measurement range, down to a range up to an impressive ratio of 1:50.

1. With minimal pressure loss, this flowmeter boasts low operating costs and significant energy-saving benefits. Within a specified range of Reynolds numbers, the output signal frequency remains unaffected by changes in the fluid's physical properties and composition. The meter coefficient is solely determined by the shape and size of the vortex shedding body, making compensation unnecessary when measuring fluid volume flow. Generally,recalibration of the meter coefficient is not required even after component changes.
