Installation Instructions

 

Installation Requirements

Piping Condition
The installation of the Low Pressure Loss Vortex Flowmeter requires specific straight pipe sections both upstream and downstream. The usual 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.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a straight pipe length of 15-20D upstream and 5-10D downstream of the sensor to achieve optimal performance.
2.
The pipe around the liquid sensor must be filled with the liquid being measured to ensure accurate readings.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations, as these can affect accuracy.
4.
The inner diameter of the straight pipe should closely match the sensor's diameter. If a perfect match is not possible, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow containing minor liquid amounts, install the sensor at a higher point. For liquid flow containing minor gas amounts, install the sensor at a lower point.
6.
For vertical pipeline installations, the sensor can be positioned without restrictions on flow direction when measuring gas. If the gas contains minor liquid amounts, the flow should be from bottom to top. For liquid flow, ensure it moves from bottom to top to avoid adding weight to the probe.
7.
For horizontal pipelines, sensors can be side-mounted regardless of the fluid type. This is especially advantageous for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to minimize temperature effects on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for most gases or superheated steam but can be used for saturated steam and high-temperature liquids or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, ensure that the insulation does not exceed one-third of the bracket height when measuring high-temperature steam.
10.
Placement of pressure and temperature measurement points. Depending on measurement needs, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream from the sensor.

Our Advantages

 

Features:

1. The structure is simple yet robust, with no moving parts, ensuring exceptional reliability and longevity.The operation is highly dependable, providing consistent performance over time.

1. Installation is straightforward, making it easy to set up, while maintenance is very convenient, reducing downtime.

1. The detection sensor does not directly contact the measured medium, guaranteeing stable performance and an extended lifespan.

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

1. Wide measurement range,covering a range down to 1:50.

1. Experience low pressure loss, reduced operating costs, and notable 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 depends solely on the vortex shedding body's shape and size, negating the need for fluid volume flow compensation.Generally, recalibration of the meter coefficient is not required after changing components, maintaining accuracy without additional adjustments.
