[Level Gauge Case] Want to reduce maintenance costs in food tanks.

[Level Gauge Case] Want to reduce maintenance costs in food tanks.

Introduction of a case where maintenance costs were reduced because frequent cleaning is not necessary!

We will introduce a case study of problem-solving for a sake manufacturer. Due to the use of a float-type liquid level gauge, significant costs were incurred every year for the maintenance and cleaning of the moving parts. Therefore, we proposed an external ultrasonic liquid level gauge. Since there is no need to install a sensor inside the tank, it is easier to maintain and does not require frequent cleaning, which can reduce maintenance costs. [Overview] ■ Case: Sake Manufacturer ■ Concern: Want to reduce maintenance costs for food tanks ■ Proposed Product: Ultrasonic Liquid Level Gauge (External Type) - By attaching the sensor to the outside of the tank, the liquid level inside the tank can be measured. *For more details, please refer to the PDF document or feel free to contact us.

SAFETY SIGHT GLASS - Safe viewing window - Liquid level gauge

SAFETY SIGHT GLASS - Safe viewing window - Liquid level gauge

A safe, undamaged peephole has been devised through a shift in thinking.

The sight glass that has been used traditionally is one where a glass plate is pressed against both sides with gaskets and secured with flange bolts and nuts. As a result, there was a significant risk of the glass inside the sight glass breaking due to the tightening conditions. This time, Chuo Rika Co., Ltd. has devised a sight glass that is safe and does not break by changing the way of thinking. It is a type that is not affected by the tightening of the gasket on the glass surface. Additionally, it does not have any impact from thermal expansion on the glass plate. For more details, please contact us or refer to the catalog.
