The "Tornado-type Level Gauge" is a level gauge that does not emit CO2, designed for small capacity tanks and drums. As the level fluctuates, the float moves up and down, rotating the shaft, which is directly connected to a pointer that displays the level. The structure that previously prevented the orientation of the memory board from being adjustable, which was a drawback of the tornado-type liquid level gauge, has been improved. By loosening the fixing screws of the memory board, it is now possible to select a position that is easy to read from any angle within 360°. 【Features】 ■ Eco-friendly level gauge ■ Durable structure ■ No CO2 emissions ■ Simple structure and installation ■ Adjustable to a position that is easy to read from 360° *For more details, please refer to the catalog or feel free to contact us.

**Overview** The TD8000 series is a two-wire submersible level gauge that uses a high-precision semiconductor pressure sensor for water level detection. Despite its slim body, it has a built-in amplifier, eliminating the need for an external converter. The detection unit can be directly suspended in water or placed on the bottom, measuring the water head pressure on the diaphragm with the semiconductor pressure sensor, which converts it into a current signal for transmission. **Features** - Pressure detection type using a semiconductor pressure sensor - Built-in amplifier, two-wire (4-20 mA) - No need for a hanging chain as the wire is internally housed within the cable - Stable installation when placed on the bottom with a detection unit stand attachment - Built-in lightning protection circuit, resistant to lightning surges - TD8300 (high precision type, accuracy ±0.10% F.S.) - TD8200 (slim type, outer diameter Ø14mm) For deep wells Ø14mm with built-in amplifier.

• Flow Meter

**Overview** This float switch offsets the weight of the guide pipe with a compression spring, utilizing the buoyancy of the float to push up and the weight of the float to push down. It detects the position of the float, which follows the liquid level, using a micro switch mechanism mounted on a sleeve, thereby obtaining ON-OFF signals. Since the sleeve is completely sealed, no steam or corrosive gases from the tank can enter the container housing the switch mechanism. By arbitrarily setting the float stopper, signals can be obtained at level positions that meet specifications. It is widely used for upper and lower limit alarms, pump control, valve opening and closing, and more.

• Piping Materials

**Overview** A current pulse is applied from the top of the probe, generating a magnetic field around the entire probe. By installing a float with a powerful magnet on the probe, it distorts the magnetic field in the vicinity. This distortion occurs only at the moment the current pulse is applied and propagates as a mechanical elastic wave towards both ends of the probe. The time of this propagation is measured to display the absolute position of the float.

• Piping Materials

【Overview】 This float switch is designed to secure a reed switch inside the stem (float guide pipe) and is activated by a magnet assembled within the float, providing an 'ON-OFF' contact output. We also offer products with pressure-resistant explosion-proof construction.

• Piping Materials

【Overview】 This float switch features a reed switch embedded in the main body that reacts to the rise and fall of the liquid level, interacting with a magnet attached to the end of the float shaft to provide ON and OFF contacts. Please design the installation position at the center of the required level. The distinction between upper and lower limits can be made simply by changing the orientation of the float. In particular, the AL-40F model is equipped with a terminal box, making it very user-friendly. ★For more details, please request documentation or download the catalog★
