About This Product

■Product overview

The pressure-sensitive surface is a thin stainless steel film, so there is no risk of leakage, so it has been used for over 20 years to prevent oil from running out in kerosene home tanks. It is often used in boiler remote controls in the kitchen to display a segment display or issue an audio warning when oil is low. Recently, it has been used to collect information on the remaining amount of kerosene by connecting it to the free terminals of the NCU of the LPG central monitoring system and to efficiently distribute kerosene. Since all of our products are made to order, we can prepare products with different settings depending on the size of the tank.
