Installation Instructions

 

Installation Requirements

Piping Condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe sections both upstream and downstream. Common scenarios are as follows (D denotes 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 the liquid flowing from bottom to top) that matches the sensor's diameter. Ensure straight pipe sections of 15-20D upstream and 5-10D downstream for optimal performance.
2.
The pipe near the liquid sensor must be fully filled with the measured liquid.
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 not feasible, opt for a slightly larger pipe with ≤3% error, not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
For horizontal pipeline installations, the most common method for flow sensors, ensure the sensor is at a higher point if the gas contains liquid and at a lower point if the liquid contains gas.
6.
For vertical pipelines, install the sensor without flow direction restrictions for gas flow. If the gas contains liquid, flow should be from bottom to top. For liquid flow, ensure it flows from bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is ideal for superheated steam, saturated steam, and low-temperature liquids. This method minimizes the temperature impact on the amplifier, making it the preferred choice if conditions allow.
8.
Inverted installation on horizontal pipelines is generally discouraged for general gases or superheated steam but is suitable for saturated steam, high-temperature liquids, or pipelines needing frequent cleaning.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
For pressure and temperature measurements near the sensor, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream, as per the measurement requirements.

Our Advantages

 

Distinctive Features:

1. Our Low Pressure Loss Vortex Flowmeter boasts a simple yet robust construction, free from moving parts, ensuring exceptional reliability and longevity.The operation of our device is impressively dependable, offering consistent performance over the long term.

1. Installation is a breeze, and maintenance is incredibly convenient, reducing downtime and operational hassles.

1. With a detection sensor that never directly contacts the measured medium, our flowmeter guarantees stable performance and an extended lifespan.

1. The output is a pulse signal directly proportional to the flow rate, ensuring high accuracy without zero drift.

1. It boasts a wide measurement range,capable of handling ranges up to 1:50.

1. Our flowmeter features low pressure loss, leading to lower operating costs and significant energy savings. 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 is solely dependent on the shape and size of the vortex shedding body, negating the need for compensation when measuring fluid volume flow. Generally,recalibration of the meter coefficient is unnecessary even after component changes.
