    How Haiphong Municipality Tracks Real-Time Pump Station Water Levels

    The Challenge

    The local municipality in Haiphong Vietnam wanted to monitor real-time water levels from several local pumping stations in their central control room using the mobile phone network.

    They needed an accurate and reliable water depth sensor that could work underwater for long periods of time.

    Monitoring water levels in pumping stations is crucial for ensuring efficient, safe, and reliable water management, preventing flooding, reducing operational costs, and minimising environmental impacts.

    The Solution

    Their monitoring system successfully uses a range of sensors, including pressure, video and Applied Measurements depth sensors. The transmitted data is displayed on 3 monitors in their control room, providing a complete overview of the conditions of each local pumping station.

    The monitoring system was commissioned in July 2023 to the fullest satisfaction of the Haiphong Municipality. Based on this experience, depth sensors for three more pump stations will be supplied for online monitoring later this year.

    We supplied the precision-engineered Pa993 series submersible depth sensor. Its high integrity waterproof rating is guaranteed thanks to its IP68 fully submersible protection to depths of up to 100 metres.

    The sensor’s impressive accuracy, better than ±0.25% of full scale, is achieved thanks to its integrated 16-bit microprocessor. This feature enables linearisation and temperature compensation, contributing to its reliable performance. In addition, the submersible level sensors are equipped with surge protection to mitigate potential effects from lightning strikes and power fluctuations.

    Its durable stainless-steel construction and built-in piezo-resistive silicon sensing element, mean these sensors guarantee long-term dependability.
