The KRAL screw meter is featured in the July issue of Measurement Technology.

The accuracy is an impressive ±0.1% R.S. with a maximum flow rate of 7500 L/min! A high-precision flow meter that is also used as a secondary standard!

The "OMG Series" screw meter volumetric flow meter has a structure that allows fluids to flow linearly, resulting in significantly lower pressure loss compared to conventional gear-type meters, and it also reduces the load inside the flow meter. The measurement accuracy is very high at ±0.1 RS, making it suitable for use as a flow reference instrument. It can measure a wide range of fluids, including high-viscosity liquids such as adhesives, sealants, PVC, and polyols, as well as low-viscosity fuels like gasoline, diesel, and kerosene. Additionally, with a variety of pickup sensors, it can accommodate a temperature range of up to -40 to 200°C. 【Do you have any of these concerns?】 - The data during high-temperature tests is poor, making accurate measurement difficult. - It breaks down quickly within 3 to 5 years due to high temperatures, necessitating replacement. - I want to measure high-viscosity fluids such as grease, adhesives, and sealants.

The OMG high and low temperature flow meter is a high-precision volumetric high-pressure flow meter. It has high measurement accuracy and can also be used as a standard device for flow calibrators.

The KRAL OMG series features a screw-type (helical gear) structure that allows fluid to flow linearly, resulting in significantly lower pressure loss compared to conventional gear meters (circular gear type), and enables high-precision measurement of ±0.1% R.S. The flow meter is calibrated at 5 mm²/s, allowing for high-precision measurement even at high temperatures (low viscosity) compared to circular gear meters. Therefore, it is hardly affected by temperature changes (changes in liquid viscosity). It can be used for a wide range of fluids, including fuels such as gasoline, diesel, kerosene, and heating oil, as well as hydraulic oils, lubricating oils, ATF, polyurethane raw materials like polyols and isocyanates, inks, adhesives, sealants, PVC, greases, and most liquids other than water. High-precision measurement of ±0.1% R.S. is possible due to the precisely machined spindle. Direction detection (forward/reverse) is also available as an option. ◎ Specifications ◎ Operating pressure: MAX 25 MPa Applicable viscosity: 1 to 1,000,000 mPas Measurement accuracy: ± 0.1% R.S.

High precision of ±0.1% RS! A volumetric flow meter of spiral gear type with intrinsic safety explosion-proof specifications.

The screw meter OME, using spiral gears, is a high-precision flow meter with an accuracy of ±0.1% RS. Since it is a volumetric type, it is less affected by changes in fluid viscosity due to temperature variations. However, an optional temperature sensor can be attached to the OME, allowing for temperature compensation to further improve accuracy. Additionally, being a volumetric type, it does not require straight pipe sections at the inlet/outlet of the flow meter. By using an aluminum body, it achieves a compact and lightweight design, making it suitable for installation in limited spaces such as engine compartments. 【Features】 ■ Explosion-proof design with intrinsic safety using Namur sensors ■ Flow range: 0.1 to 525 l/min (4 models) ■ Operating temperature: 0 to 80℃ ■ Operating pressure: Max 4MPa ■ Measurement accuracy: ±0.1% R.S. (1:10 range) ■ 90° phase difference pulse output for two-phase (optional) *For more details, please refer to the PDF document or feel free to contact us.

The flow monitor is an oil/water flow meter that can be used at high pressure and high temperature. It is a visual type flow meter that does not require power, and the installation orientation can be vertical or horizontal.

Compatible with high pressure such as hydraulic/water pressure Also supports high-temperature specifications for various performance tests and durability tests The flow monitor is a flow meter for oil that is compatible with high pressure and high temperature. The flow monitor operates by the internal magnet being pushed up by the flow of fluid, and the pointer moves in conjunction with the magnet to indicate the flow rate. Since oil does not flow directly over the scale section, it is easy to read the scale. It can be installed in any orientation, either vertically or horizontally. The standard type can handle temperatures up to 116°C, but we also offer high-temperature "H" series and ultra-high-temperature "J" series. Additionally, we have a dedicated "P" series for aircraft hydraulic fluids. The scale for oil has been pre-calibrated based on a specific gravity of 0.873 and a viscosity of 40 mm²/s, so conversion from the water scale is unnecessary. Models that accommodate both forward and reverse flow are also available. (BI) *It can also be used for water. (Water scale compatible) Please contact us for inquiries regarding transmitters.

In civil engineering sites such as mountainous areas and construction sites, it may be necessary to use wooden boards on slopes or inclined access roads. Hyper CLT boards are civil engineering materials utilizing wood CLT, which can be laid not only on flat ground but also on sloped terrain. They can be used for temporary roads, access routes, heavy machinery entry paths, and measures against muddy conditions, creating a driving environment that takes advantage of the unique surface characteristics of wood. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery, which is a notable feature for maneuverability in narrow sites. This wooden board is registered as a technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS system as "TH-250021-A," and can also be utilized for safety measures and innovative ideas in public works.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be performed even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.
