Installation Instructions

 

Installation Requirements

Piping Condition
To ensure optimal performance of the Gas Vortex Flowmeter with Low Pressure Loss and High Accuracy, specific installation criteria regarding straight pipe sections must be adhered to. Here are the standard scenarios (D represents the pipe's 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 horizontal, vertical, or inclined pipes (with fluid flowing bottom to top) that match the sensor's diameter. Ensure there are straight pipe sections both upstream and downstream: 15-20D for the front and 5-10D for the rear.
2.
The pipeline near the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of straight pipe sections should closely match the sensor diameter. If not, use a slightly larger diameter pipe with a tolerance of ≤3% and no more than 5mm. Avoid installations in areas with strong electromagnetic interference, cramped spaces, or places difficult to maintain..
5.
Horizontal pipeline installation is prevalent for flow sensors. For gas flow measurements with minimal liquid, place the sensor at a higher point. Conversely, for liquid flow with minimal gas, position the sensor at a lower point in the pipeline.
6.
For vertical pipeline installations: When measuring gas, install the sensor vertically with no flow direction constraint. If gas contains some liquid, ensure the flow is from bottom to top. For liquid flow, it should also move from bottom to top to prevent additional load on the probe.
7.
Side mounting of sensors on horizontal pipelines is viable for various fluids, including superheated steam, saturated steam, and low-temperature liquids. Side installation is preferred, if possible, to reduce temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipes is generally discouraged. It's unsuitable for general gases or superheated steam but can measure saturated steam and high-temperature liquids or in situations requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers: When measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Choosing pressure and temperature measurement points: Based on measurement needs, place the pressure point 3-5D downstream of the sensor and the temperature point 6-8D downstream.

Our Advantages

 

Features:

1. The structure of our Gas Vortex Flowmeter is ingeniously simple yet exceptionally robust. With no moving parts, it ensures high reliability and promises long-term durability.Operation of this flowmeter is not only highly dependable but also incredibly efficient.

1. Installation is a breeze, and maintenance is highly convenient, saving you time and effort.

1. The detection sensor is designed to avoid direct contact with the measured medium, guaranteeing stable performance and an extended lifespan.

1. It features an output pulse signal that is directly proportional to the flow rate, featuring no zero drift and ensuring high accuracy.

1. Our flowmeter boasts a wide measurement range, ranging down up to 1:50.

1. Experience low pressure loss, reduced operating costs, and substantial energy-saving benefits. Remarkably, within a specific range of Reynolds numbers, the output signal frequency remains unaffected by variations in the fluid's physical properties and composition. The meter coefficient's fidelity is tied solely to the vortex shedding body's shape and size, effectively eliminating the need for compensation in fluid volume flow measurements.Typically, there is no need to recalibrate the meter coefficient even after component changes.
