Installation Instructions

 

Installation Requirements

Piping condition
The installation of the Easy Install Vortex Flowmeter requires specific straight pipe sections before and after the device, ensuring accurate measurements. The common configurations are listed below (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 can be horizontal, vertical, or inclined (with liquid flowing from bottom to top). The pipe must match the sensor diameter and include straight sections of 15-20D upstream and 5-10D downstream to ensure precision.
2.
Ensure the pipe near the liquid sensor is fully filled with the liquid being measured to maintain accuracy.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations to prevent measurement errors.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If not possible, use a slightly larger diameter with an error margin of ≤3% and not exceeding 5mm. Do not install in areas with strong electromagnetic interference, cramped spaces, or where maintenance is hard..
5.
Horizontal pipeline installation is the most common. For gas flow with minor liquid content, place the sensor at the highest point. For liquid flow with minor gas content, place it at the lowest point to ensure proper measurement.
6.
For vertical pipelines, if measuring gas flow, the sensor can be installed regardless of flow direction. If the gas contains liquid, flow must be from bottom to top. When measuring liquid flow, ensure it flows from bottom to top to avoid extra weight on the probe.
7.
For side installations on horizontal pipelines, sensors should be side-mounted regardless of the fluid type, particularly for superheated steam, saturated steam, and low-temperature liquids. This minimizes temperature effects on the amplifier.
8.
Inverted sensor installations on horizontal pipelines are generally not recommended, except for measuring saturated steam and high-temperature liquids or in cases where pipelines require frequent cleaning.
9.
For pipelines with insulation layers, especially for high-temperature steam, ensure the insulation does not exceed one-third of the bracket height to maintain accuracy.
10.
When pressure and temperature measurements are required near the sensor, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.

Our Advantages

 

Outstanding Features:

1. Boasting a simple yet highly robust structure, this flowmeter features no moving parts, ensuring exceptional reliability and long-term durability.Its operation is impressively dependable.

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

1. The detection sensor remains isolated from the measured medium, guaranteeing stable performance and an extended lifespan.

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

1. It covers a wide measurement range,scaling from as low as 1:50.

1. With minimal pressure loss and low operating costs, this flowmeter provides remarkable energy-saving benefits. Over a certain range of Reynolds numbers, the signal frequency is unaffected by changes in the fluid's physical properties and composition. The meter coefficient is determined by the shape and size of the vortex shedding body, eliminating the need for fluid volume flow compensation. Typically,there's no need for recalibrating the meter coefficient after component changes.
