Installation Instructions

 

Installation Requirements

Piping Condition
The installation of the vortex flowmeter necessitates a certain length of straight pipe both upstream and downstream. Here are the typical scenarios (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 pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor's diameter. Ensure there is a sufficient straight pipe length: 15-20D upstream and 5-10D downstream.
2.
The pipe near the liquid sensor should be filled with the liquid being measured.
3.
Avoid installing the sensor on a pipe experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor's diameter. If not, use a slightly larger diameter with an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow with minor liquid content, install the sensor at the highest pipeline point. For liquid flow with minor gas content, install the sensor at the lowest pipeline point.
6.
Vertical pipeline installation for gas flow can be unrestricted in direction. For gas with minor liquid content, ensure the flow is from bottom to top. For liquid flow, positioning should be bottom to top to avoid undue weight on the probe.
7.
Side installation on horizontal pipelines is viable for all fluids, including superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred to minimize temperature impacts on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. While unsuitable for general gases or superheated steam, it can measure saturated steam and high-temperature liquids, especially in conditions requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
Select pressure and temperature measurement points wisely: 3-5D downstream for pressure and 6-8D downstream for temperature, based on measurement needs.

Our Advantages

 

Features:

1. The structure is simple yet robust, designed with no moving parts to ensure high reliability and long-term stability. Operation remains exceptionally dependable, giving you peace of mind.

1. Installation is a breeze, and maintenance is hassle-free, saving you time and effort.

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

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

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

1. With low pressure loss, reduced operating costs, and substantial energy-saving benefits, the flowmeter is highly efficient. Within a specific 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 related to the shape and size of the vortex shedding body, eliminating the need for compensation when measuring fluid volume flow. Typically, recalibration of the meter coefficient is unnecessary even after component changes.
