Certifications PACKING & SHIPPING DETAILS
We will deliver your order at the earliest date as required by you, ensuring timely and efficient service. Installation Instructions Installation Requirements
Piping condition
The installation of vortex flowmeter requires a certain straight pipe section before and after, and the common situations are as follows (D is 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 pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and has the same diameter as the sensor. There should be a certain length of straight pipe upstream and downstream of the sensor, with the length meeting the requirements of 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
The pipe near the liquid sensor should be filled with the liquid being measured.
3.
The sensor should not be installed on a pipe with strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should be as consistent as possible with the sensor diameter. If they cannot be the same, a slightly larger diameter pipe should be used, with an error of ≤3% and not exceeding 5mm. The sensor should not be installed in locations with strong electromagnetic interference, limited space, or inconvenient maintenance. Installation requirements.
5.
Horizontal pipeline installation is the most common method for flow sensors. When measuring gas flow, if the gas being measured contains a small amount of liquid, the sensor should be installed at a higher point in the pipeline. When measuring liquid flow, if the liquid being measured contains a small amount of gas, the sensor should be installed at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines. When measuring gas flow, the sensor can be installed on a vertical pipeline with no restriction on flow direction. If the gas being measured contains a small amount of liquid, the gas flow should be from bottom to top. When measuring liquid flow, the liquid flow should be from bottom to top to avoid additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines. Regardless of the fluid being measured, sensors can be side-mounted on horizontal pipelines, especially when measuring superheated steam, saturated steam, and low-temperature liquids. If conditions allow, side mounting is preferred as it minimizes the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines. This installation method is generally not recommended. It is not suitable for measuring general gases or superheated steam. It can be used for measuring saturated steam and is suitable for measuring high-temperature liquids or situations where pipelines need frequent cleaning.
9.
Installation of sensors on pipelines with insulation layers. When measuring high-temperature steam, the insulation layer should not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points. Depending on the measurement requirements, when pressure and temperature need to be measured near the sensor, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream of the sensor.

COMPANY AND FACTORY PICTURE:
Our Advantages Features: The structure of our High Accuracy Vortex Flowmeter for Steam with Low Pressure Loss is ingeniously simple yet incredibly robust. With no moving parts, it boasts high reliability and ensures long-term stability.Operation is highly dependable, providing peace of mind and consistent performance. Installation is a breeze, and maintenance is exceptionally convenient, saving you time and effort. The detection sensor is designed to avoid direct contact with the measured medium, ensuring stable performance and extending the lifespan of the flowmeter. Outputs a pulse signal that is accurately proportional to the flow rate, with zero drift and unmatched accuracy. Wide measurement range, extending down up to an impressive ratio of 1:50. Enjoy low pressure loss, reduced operating costs, and significant energy savings with our flowmeter. 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 related to the shape and size of the vortex shedding body, eliminating the need for fluid volume flow compensation. Typically, recalibration of the meter coefficient is unnecessary even after component changes.
