With conventional liquid level gauges, alarm signals were unstable and could be affected by noise and other interference.
As a result, signal reliability was inconsistent.
ヒアリング
Hearing
In conventional level monitoring, alarm signal stability varied due to factors such as noise.
A system that is resistant to external environmental influences and can reliably output alarm signals was therefore required.
ソリューション選定
Solution selection
Adopted a direct-acting float-type liquid level gauge. By using mechanical switches, the system is resistant to noise and can reliably transmit alarm signals.
ソリューション検討・評価
Solution review & evaluation
・False alarm signals were eliminated, enabling stable monitoring.
・Liquid levels can be measured with high precision, improving the reliability of facility operations.
製造
Manufacturing
To achieve high measurement accuracy, we pursued optimization of a structure in which the float moves stably up and down.
Through detailed design adjustments and repeated verification, we created a specification that combines stable operation with high precision.
納品
Delivery
We continuously enhanced quality while also accommodating witness inspections by customers, thereby improving product reliability.
The gauge now delivers consistent performance and is highly regarded as a reliable liquid level monitoring device.
