【Installation method is flexible!】Pressure transmitter type liquid level gauge P series

【Installation method is flexible!】Pressure transmitter type liquid level gauge P series

Robustness type commonly used in applications with high humidity and significant vibrations, such as ships, due to factors like vibration, seawater resistance, high temperature and humidity, and intense liquid agitation.

The liquid pressure in the tank is detected by a diaphragm, and the capacitance changes as the distance between the two electrodes arranged in parallel inside changes. An analog signal of 4-20 mA is also output from the center, transmitting and displaying the liquid level in the tank to monitoring panels, etc. It is possible to provide not only the sensor but also a system that includes a display unit. <Features> ■ Compact size and robust structure make installation and maintenance easy. ■ The sensor part is protected, making the diaphragm less prone to damage. ■ Various mounting methods are available, allowing for adaptation to different installation environments. *For more details, please refer to the PDF materials or feel free to contact us.

Easy to install! Maintenance-friendly liquid level gauge 'PCT'

Easy to install! Maintenance-friendly liquid level gauge 'PCT'

The completely sealed structure blocks the air inside the tank! It can be installed at a scale of 1/2 or less, allowing for the mounting of guide rails and scale plates in an easily visible position.

The 1/2 scale liquid level gauge with guide rail PCT (A) is a completely sealed liquid level gauge that does not allow air from the tank to escape to the outside. It detects the liquid level using a float that is buoyed in the tank, and displays the liquid level through a weight directly connected to a wire. The liquid level is indicated using a balance weight connected to the float. Additionally, for tall tanks, a scaled guide rail and scale board can be installed, allowing for placement in an easily visible position. ★ For heated tanks It prevents the retention of vapor, condensate, and mist within the tank. 【Features】 ■ Completely sealed, preventing air from escaping the tank ■ Uses a scaled scale board that can be monitored at eye level ■ The scale board is large and easy to see from a distance ■ No power source or air source required for operation High installation flexibility, energy-saving, and economical ■ Contact installation is possible, allowing for alarm and control settings *For more details, please download the PDF or feel free to contact us.

[Liquid Level Gauge Example] I want to see the liquid level at eye level.

Introducing a case where the display could be checked at eye level in the ship's engine room tank!

We would like to introduce a case study on solving issues with marine engine room tanks. Previously, crew members had to climb ladders to check the liquid level in the tanks using glass level gauges, which led to the concern of wanting to "see the liquid level at eye level." As a solution, we adopted a box-type float level gauge, allowing for the display to be checked at eye level, which improved efficiency and enhanced work safety. 【Overview】 ■ Case: Marine engine room tank ■ Concern: Wanting to see the liquid level at eye level ■ Proposed product: Float level gauge - By installing the tank level indicator in an easily visible position, safe confirmation of the liquid level can be achieved. *For more details, please refer to the PDF document or feel free to contact us.

[Liquid Level Measurement Example] Transparent liquid, difficult to see the liquid level.

No power supply needed for easy installation! With a diaphragm-type liquid level gauge, you can see the liquid level at a glance in one location.

We would like to introduce a case study that solved the concerns of a chemical manufacturer (sodium hypochlorite tank). There was an issue with using a glass liquid level gauge, as the liquid was transparent and difficult to see. Therefore, we proposed a diaphragm liquid level gauge. It allows for easy visibility of the liquid level at a glance from one location and is also easy to install. [Overview] ■ Case: Chemical manufacturer (sodium hypochlorite tank) ■ Concern: Transparent liquid makes it difficult to see the liquid level ■ Proposed product: Diaphragm liquid level gauge - No power supply required and easy to install *For more details, please refer to the PDF document or feel free to contact us.

[Liquid Level Measurement Example] I want to measure the liquid level of highly corrosive liquids without direct contact with the liquid.

By installing a radar level gauge on the tank top, you can measure without coming into contact with the liquid!

We would like to introduce a case that solved issues with tanks containing highly corrosive liquids. "There was a problem where the parts in contact with the liquid in the type that measures liquid levels by direct contact are prone to damage due to corrosion and need to be replaced frequently." Therefore, we proposed a radar level gauge. By installing it on the tank top, measurements can be taken without contacting the liquid. 【Overview】 ■ Case: Tank for highly corrosive liquids ■ Issue: Want to measure the liquid level without direct contact with the highly corrosive liquid ■ Proposed product: Radar level gauge - Can measure the liquid level without direct contact with the liquid *For more details, please refer to the PDF document or feel free to contact us.
