[Liquid Level Gauge Case Study] Streamlining Tank Liquid Level Measurement Operations and Achieving Accurate Measurements

[Liquid Level Gauge Case Study] Streamlining Tank Liquid Level Measurement Operations and Achieving Accurate Measurements

Reduced conventional measurement time by approximately 75%! A case where the liquid level was accurately measured without reacting to the foam.

We would like to introduce a case study that addresses the challenges of improving the efficiency of tank liquid level measurement operations and achieving accurate measurements. In the fuel tank, bubbles formed on the liquid surface, and when measured with conventional scales, the height of the bubbles was also counted, resulting in paying for that volume as fuel costs. To solve this, we introduced the smart sounding scale "Honesty." It does not react to bubbles and can accurately measure the liquid level, reducing the conventional measurement time by about 75%. 【Overview】 ■ Case Study: Marine Fuel Tank ■ Challenge: Improving the efficiency of tank liquid level measurement operations and achieving accurate measurements ■ Proposed Product: Smart Sounding Scale "Honesty" - The sensor at the tip of the measuring device does not react to bubbles and accurately captures the actual liquid level. - Over 1,000 units have already been delivered and installed on more than 500 vessels. *For more details, please refer to the PDF document or feel free to contact us.

Nihon Keiki Co., Ltd. Liquid Level Gauge Comprehensive Catalog

Nihon Keiki Co., Ltd. Liquid Level Gauge Comprehensive Catalog

We offer a variety of liquid level gauges made in Japan, focusing on easy-to-maintain and safe magnetic liquid level gauges, with a commitment to in-house production of every single component.

【A Must-See for Companies Measuring Liquid Levels in Plants and Tanks】 We have received feedback from companies using the traditional Klinger type (glass sight glass) regarding: - "The glass is heavy and difficult to maintain." - "It has broken during earthquakes and other disasters, causing concerns." - "Ultraviolet (UV) light has penetrated through the sight glass, altering the liquid." Based on these requests, Japan Instrument has developed and produced the "Magnetic Liquid Level Gauge." 【Features of the Magnetic Liquid Level Gauge】 - No maintenance required, such as regular cleaning like glass windows. - Weighs less than half of the Klinger type, making assembly and inspection easy. - Usable with dark, viscous fluids like heavy oil. Our comprehensive catalog includes a variety of products, such as a safe magnetic liquid level gauge that works with any liquid, a simple round glass liquid level gauge for low pressure, and a versatile Klinger type liquid level gauge for medium pressure. Since we manufacture in-house, we can produce liquid level gauges tailored to your specifications. 【Featured Products】 - Liquid Level Gauges - Remote Measurement Systems - Sight Glasses ◆ Exhibiting at Measurement Expo 2014 in Osaka ◆ We will be exhibiting at the Measurement Expo held at Grand Cube Osaka from November 19 (Wednesday) to 21 (Friday).

Klinger type liquid level gauge "Reflective type, Transparent type, Special type"

Klinger type liquid level gauge "Reflective type, Transparent type, Special type"

Using hard reinforced glass with a small thermal expansion coefficient and excellent pressure resistance, heat resistance, and corrosion resistance.

The Klinger-type liquid level gauge uses hard reinforced glass with a small thermal expansion coefficient and excellent pressure resistance, heat resistance, and corrosion resistance. It has high airtightness due to high-strength bolts and features a check ball in the valve, making it suitable for use in tanks such as pressure vessels. The reflective liquid level gauge has five V-shaped grooves in the gauge glass, and due to the prism effect, the gas phase appears white while the liquid phase appears black without diffuse reflection, allowing for a clear view of the liquid level. The sight glass liquid level gauge uses two pieces of gauge glass and has a structure that allows visibility to the opposite side of the main body. It can be protected with materials such as mica or fluororesin to prevent corrosion of the glass by alkalis. Additionally, the lighting device makes it easier to determine the liquid level, and it has a structure that is stronger against pressure than reflection. 【Product Lineup】 ○ Reflective liquid level gauge series: RZ (general type) ○ Sight glass liquid level gauge series: TV (general type) ○ Special types → RZ-NF/TV-NF (low-temperature type): Equipped with acrylic pieces to prevent fogging in the visible area → RZ-W/TV-W (staggered type): Allows for a wide range of visible lengths with no invisible parts → RZ-C (acid-resistant type): Features Teflon lining in the liquid contact area to improve acid resistance For more details, please contact us or download the catalog.
