We would like to introduce our "IoT Remote Monitoring Solution." By implementing the system, data from sensors and measuring instruments at each location can be aggregated, visualized, analyzed, and recorded. The cloud measurement data is compiled and displayed in a format suitable for user operations, enabling various applications to be utilized. 【System Features】 ■ A total solution provided from measuring instruments to gateways and the cloud ■ Quick implementation, with operations starting in as little as one day ■ Seamless connection between devices and the cloud ■ Management and monitoring of device settings and statuses can be done from the cloud ■ Capable of handling diverse data that matches the applications required by users *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where our temperature-controlled warehouse's temperature and humidity remote monitoring and anomaly notification system was implemented for customers in the warehouse and logistics industry. Previously, anomalies could not be detected immediately due to only a few visual checks per day, and confirmation was done via phone during trouble occurrences. Additionally, there was a challenge that immediate alarms triggered by the loading and unloading of goods would disrupt operations. After the introduction of this system, real-time anomaly detection became possible, allowing personnel at headquarters to monitor from a distance. A delay function to accommodate temperature fluctuations caused by door openings and closings has also been incorporated, contributing to improved temperature management levels. 【Case Overview】 ■ Previous Specifications: Temperature checks through visual inspection several times a day and paper records ■ Challenge: Wanted to grasp the temperature of warehouses dispersed across the site in real-time and detect anomalies ■ Solution: Proposed a system configuration that sends and records the analog output signal from the control panel temperature controller to the cloud and notifies via email in case of deviations ■ Implementation Effect: Real-time anomaly detection is possible, and the elimination of paper records *For more details, please feel free to contact us.

We would like to introduce a case where our automatic meter reading and remote monitoring system was implemented for a customer managing sewer meter readings across the country. Previously, regular on-site visits and visual meter readings were conducted, but the costs and labor associated with traveling for remote meter reading were significant, leading to the challenge of wanting to conduct remote monitoring at a lower cost. After implementation, we built a system that counts the flow accumulation pulses from the sewer meters using the "WMB-DI16" and accumulates data in an IoT gateway. By collecting data remotely via a fixed IP SIM, we successfully reduced travel expenses. [Case Overview] ■ Previous Specifications: Regular on-site visits and visual meter readings ■ Challenge: Desire to conduct remote monitoring at a lower cost to reduce travel expenses ■ Solution: Implementation of the IoT gateway and pulse input node "WMB-DI16" ■ Customer Feedback: The ease of setting up and implementing the system without programming was highly valued. *For more details, please feel free to contact us.

We would like to introduce a case where our on-premises immediate notification system for equipment failure anomalies was implemented by an aquaculture business. In the event that equipment anomalies or failures go unnoticed for an hour, it could lead to the death of juvenile fish and result in damages amounting to hundreds of millions of yen. Therefore, there was a request to issue immediate alarms upon the occurrence of equipment anomalies. After implementation, we established a system that sends email alerts using an on-premises configuration with a SIM card that has a global IP, tailored to prioritize cost. We confirmed normal operation during test runs and have completed preparations for full-scale operation. 【Case Summary】 ■ Challenge: To issue immediate alarms upon the occurrence of equipment anomalies ■ Solution: Introduction of an IoT gateway and contact input node "WMB-DI16" ■ Customer Feedback: The ability to significantly reduce monthly operational costs by using an on-premises configuration was highly valued. *For more details, please feel free to contact us.

We would like to introduce a case where a pump manufacturer implemented our predictive maintenance and fault location identification system for remote installation pumps. Previously, regular on-site inspections and reactive maintenance were conducted, but there were inefficiencies such as having to return without identifying fault locations before going on-site, or returning from regular inspections without any abnormalities. After implementation, we utilized a group of sensors, including "Mibunroku Cloud" and IoT gateways, to measure water levels and current values, and established a system that sends alarm emails when threshold anomalies occur, progressing towards reducing unnecessary on-site visits. 【Case Overview】 ■ Previous Specifications: Regular on-site inspections and visual checks, reactive maintenance ■ Challenges: Inefficiencies arose due to staff shortages ■ Solution: Implementation of a group of sensors such as "Mibunroku Cloud" and IoT gateways ■ Customer Feedback: The ability to collect diverse measurement data from a single company was highly valued *For more details, please feel free to contact us.

We would like to introduce a case where our power monitoring system was implemented by an environmental and energy consulting company. The in-house developed gateway and cloud system that were previously used had aged, and the other company's measuring devices that were being used were discontinued, necessitating the need for alternative products to handle new projects. After implementation, we applied our own power meters along with the "WGWB" and "Mibunroku Cloud" to new projects. In locations where existing products from other companies were installed, we successfully built a hybrid configuration, establishing a flexible monitoring system. [Case Overview] ■ Previous Specifications: Other company's power meters and in-house developed gateway/cloud system ■ Challenge: Need for alternatives due to aging and discontinuation ■ Solution: Introduction of multi-circuit power meters and IoT gateway "WGWB" ■ Customer Feedback: The flexibility to connect and integrate other company's devices into the same gateway was highly valued. *For more details, please feel free to contact us.

The "WPC Series" is a product that measures electrical power in various locations.

The "WKM Series" is a product that measures and displays various power data on an LCD screen. Returning to the fundamental question of "What is truly required from a meter?", we are committed to ensuring that even a simple meter can display information in a highly visible manner. It is equipped with various features such as selectable output options, a setting copy function, and a simulated input/output test function. 【Features】 ■ Exceptional visibility with white LED backlight ■ Safety range is clearly indicated by a guideline (safety point setting) ■ Even easier to read with a large approximately 4.2-inch LCD displaying four elements simultaneously ■ Multi-range compatible, allowing for free setting of voltage and phase line classification ■ LED backlight blinks when an alarm is triggered *For more details, please download the PDF or feel free to contact us.
