Hense Wägetechnik introduces new economic Solid Flow Meter
Cost-effective ”eco-FlowSlide” complements the flow measurements range for free-fall appli
With the ”Eco-FlowSlide” Hense Wägetechnik complements the series ”Baby-FlowSlide”, ”FlowSlide” and ”Maxi FlowSlide” with a flow measurement system, which is made entirely of stainless steel (1.4301 or 1.4721) and is nevertheless priced significantly cheaper than the established standard FlowSlide devices.
How is that possible? The standard FlowSlide systems are manufactured with the highest possible precision on 5-axis machining centers.
For weight reasons, 12 mm thick plates made of high-quality, seawater resistant aluminium are used. The manufacturing tolerances are below 0.02 mm. Due to the parallelism of the screwed components, no additional seals are required.
The product-touching parts of the FlowSlide measuring system consist of polished stainless steel or wear-resistant ”HARDOX 400”. The new system of inexpensive, edged stainless steel sheets, does not quite reach the high measuring accuracy of the standard FlowSlides. This is caused by the production related tolerance of edged steel parts.
The high manufacturing precision and stability of the standard systems also have some disadvantages:
1. The machine running times on the cost-intensive machines significantly increase production costs.
2. A system completely in stainless steel instead of aluminum is very heavy and only useful up to 50 m³/h.
3. Some users do not really need the high measurement accuracy of +/-99.5%.
In order to meet the strong demand for cheaper systems made of painted structural steel or stainless steel, Hense Wägetechnik decided to develop a version based on folded steel sheet.
Since the ”inner life” is structurally identical, the prototype was built within a short time - the test results of the Hense Wägetechnik test stand are expected to be promising:
The stainless steel version made of folded sheet metal can meet the standard requirements of most users with a guaranteed tolerance within +/-1%.
In addition to the cost advantage of approx. 20 to 30%, the ”eco-FlowSlide” can be made of various stainless steel qualities for the food sector.
The new ECO-FlowSlide will be offered in the following sizes:
- ECO-FlowSlide 10 (EFS10 max. 10 m³/h volumetric capacity)
- ECO-FlowSlide 25 (EFS25 max. 25 m³/h volumetric capacity)
- ECO-FlowSlide 50 (EFS50 bis max. 50 m³/h volumetric capacity)
Further sizes (up to 5 m³/h and up to 80 m³/h) are currently in preparation.
