SS304 Stainless Steel Honeycomb Flow Straightener For Fluid Measurement Meter
Stainless Steel Honeycomb Flow Straightener For Fluid Measurement Meter
Stainless Steel Honeycomb Flow Straightener for Fluid Measurement Meter is used for achieving ideal measurement results. Meters require that the water enters the turbine of the water meter in an unimpeded flow pattern.
In order to ensure this, an installation of honeycomb straightener at inlet and outlet zones are required. There causes problems at theT-pieces, elbows or partially open valves that eddies in the water and an irregular flow-rate profile may be created. When this turbulence reaches the meter, it will have a long-term effect on the measurement results. It is the honeycomb rectifier which can solve this kind of technical problem.
The detailed structure is as below:
It is the 32 square-axial channels rectify the turbulence of the water inside the pipeline.
A punched disc will be installed at the outlet of the honeycomb, with the open cross-section of which is equal to approximately half the cross-section of the pipe. The water flowing in is braked and the subsequent square channels rectify any remaining turbulence.
Pressure loss due to the honeycomb rectifier is approximately 0.1 bar at a flow-rate of 3 m/sec.
The metal flange of the punched disc serves to attach the rectifier between two flanges and the honeycomb unit faces downstream.

Properties
Welded honeycomb core, no matter what material is, such as aluminum, stainless steel, steel, titanium etc, possesses better mechanical properties against regularly produced glued honeycomb core. So it performs significantly better again the common honeycomb bonded by adhesive on strength, modulus, corrosion resistance, dimensional stability etc. However, generally, these critical performance variables should be evaluated: material, airflow and attenuation.
1. Material Composition
Stainless steel grade should be considered according to the real application. Custom materials other than stainless steel are available upon request. Here are the parameters need to be evaluated:
Durability
Material type and grade is the first aspect to be evaluated then plating, discussed in depth later, can improve durability.
Weight
Material, structure and thickness of the material can affect the total part weight.
2. Corrosion resistance
Typically brass and stainless steel should be used in slashing environments. Plating or nonconductive surface coatings can improve corrosion resistance for all honeycomb types.
3. Airflow & Attenuation
Airflow and attenuation are inversely proportional. Infinitely large honeycomb cells result in infinitely small attenuation (and vice versa). Typically, as a design baseline, airflow performance requirements are calculated to meet thermal performance needs for the assembly that the vent is to be installed onto. Once airflow is determined, attenuation and other requirements can be evaluated. Standard cell sizes for honeycomb are 1/16", 1/8" and 1/4", with 1/8" being most common. Standard thicknesses are 1/4," 1/2" and 1," with 1/4" being most common.
