What types of Vortex Flowmeter Housings can Shata Machinery manufacture?
How Shata Machinery Implements Quality Control for Cast Aluminum Vortex Flowmeter Housings
All gravity-cast aluminum alloy vortex flowmeter housings undergo rigorous multi-stage inspections prior to shipment:
Aluminum alloy composition analysis: Spectroscopic testing to verify that the alloy element ratios meet specifications.
Visual defect inspection: Checking for flaws such as internal porosity, cracks, shrinkage cavities, and sand inclusions within the flow channel.
Full dimensional inspection: Verification of all flange, thread, and sensor mounting dimensions using calipers and CMM (Coordinate Measuring Machines).
Hydrostatic leak testing: Each housing undergoes hydrostatic testing at 1.5 times the nominal pressure to ensure no leakage in the flow channel.
Metallographic sampling: Random inspection of critical pressure-bearing components to verify internal casting density.
Assembly fit test: Trial assembly with standard vortex shedding bodies and sensor components to ensure smooth installation.
Finished product batch sampling: Random sampling to ensure consistent quality standards across the entire batch.

FAQ
Q: What casting process is used for the flow meter's aluminum alloy housing?
A: We operate three distinct production lines-gravity casting, die casting, and sand casting-allowing us to recommend the optimal process based on the client's budget, surface quality requirements, dimensions, and operating conditions.
Q: Can you manufacture the housing if we only have a physical sample but no technical drawings?
A: Yes. Our technical team can scan the sample to generate a 3D digital model, develop the sand mold, and proceed with gravity casting production.
Q: Which aluminum alloy is used as the standard for these flow meter castings?
A: The standard material is A356 (ZL114) aluminum alloy; however, we can switch to ZL104 or a custom alloy to meet specific requirements for wear resistance or high-temperature performance.
Q: Does every casting undergo pressure leakage testing?
A: Yes. All finished housings undergo a hydrostatic pressure test at 1.5 times the nominal pressure to ensure there are no leaks in the flow channels.
Q: Do you accept small-batch sample orders for the development of new flow meter models?
A: We support small-batch gravity casting for prototypes; once the samples are approved, we can transition to continuous mass production.
Q: What pressure ratings can your gravity-cast aluminum housings withstand?
A: Standard specifications include PN1.6, PN2.5, and PN4.0; we can also customize the casting structure with increased wall thickness to meet higher pressure requirements.
Q: Can the cast aluminum housing be used for high-temperature steam measurement?
A: We manufacture reinforced gravity-cast housings designed for high temperatures, capable of handling media temperatures up to 260°C, making them suitable for steam metering equipment.
Q: What size range of vortex flow meter housings can be produced via gravity casting?
A: Our production lines cover everything from small DN15 meter bodies to large DN300 industrial measuring tube housings.
