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).

Liquid level gauge customizable from 1 point.

Liquid level gauge customizable from 1 point.

It's possible precisely because we produce it in-house. We offer full customization from parts.

【Want to Measure Liquid Level】 The thickness and design of the glass window vary depending on the tank, piping, and fluid (quality, color, characteristics). Since our company assembles the parts in-house, we can customize liquid level gauges and surrounding components to meet the needs of each client. 【Recommended for the following people!】 - Those who want to measure liquid levels but are struggling with existing products due to structural issues. - Those who cannot accurately measure liquid volume because the glass window is dirty and hard to see through. If you are having trouble with Klinger-type liquid level gauges, magnetic liquid level gauges, or various sensors and surrounding components, please consult with us.

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.
