日本エンヂニヤ List of Products and Services

We would like to introduce the "Instrumentation and Control Equipment" that we handle. In plants such as water supply facilities, we provide sensors that act as the eyes and ears in place of humans, and loop devices that convert and transmit signals from the sensors like nerves. Furthermore, we handle various instrumentation devices, including control devices that process and summarize that information, and power supply devices that supply power to each unit. Of course, we not only sell but also carry out installation and adjustments. Please feel free to consult us. 【Products We Handle (Excerpt)】 ■ Sensors - Flow meters (electromagnetic flow meters, Woltman-type flow meters, etc.) - Level gauges (submersible level gauges, capacitive level gauges, ultrasonic level gauges, etc.) - Pressure gauges - Thermometers ■ Loop devices, control devices, panels - Isolators, signal converters - Indicators (wide-angle indicators, pargraph indicators) - Setting devices *For more details, please refer to the PDF document or feel free to contact us.

In the rapid filtration facility, there were significant fluctuations in the raw water turbidity during rainy and sunny weather, and the amount of coagulant injected was adjusted based on the experience and intuition of the personnel in charge. Therefore, a control panel was equipped with a regulator to implement control of the coagulant injection amount. By combining the conventional intake flow rate with the raw water turbidity and based on the results of repeated jar tests, an appropriate injection amount corresponding to the raw water turbidity was determined, stabilizing floc formation. There is no longer any concern about changes in weather or fluctuations in raw water turbidity, and the concerns about aluminum detection have also been resolved, resulting in stable filtered water quality. [Overview] ■ Location: Somewhere in Nagano Prefecture ■ Implementation period: Fiscal Year 2011 ■ Construction summary - Modification of the control panel related to the signal acquisition of the raw water turbidity meter and intake flow meter *For more details, please refer to the PDF document or feel free to contact us.

In the rapid filtration facility, there were significant fluctuations in the turbidity of the raw water taken from the river, causing concerns about weather and raw water quality. The amount of coagulant injected was adjusted based on the experience and intuition of the personnel in charge. To address this, we installed a "raw water turbidity meter" and a "water intake flow meter," and equipped the control panel with a touch panel and PLC to control the amount of coagulant injected. By determining the appropriate injection amount based on the raw water turbidity, the formation of flocs became stable. We no longer had to worry about changes in weather or fluctuations in raw water turbidity, and concerns about aluminum detection were also alleviated.
