LEWA Smart Monitoring

LEWA Smart Monitoring is a monitoring system consisting of sensors, a programmable logic controller (PLC), an industrial PC (IPC) and data analysis for new and existing pumps. The system determines characteristic values and key performance indicators.

It is suitable for the LEWA ecoflow process and triplex diaphragm metering pump series. The focus of the system are critical and permanent applications from chemical, pharma or beverage industries.

LEWA Smart Monitoring

With digital pumps for more efficiency, system availability and profitability of the entire production.

LEWA Smart Monitoring is a monitoring system consisting of sensors, a programmable logic controller (PLC), an industrial PC (IPC) and data analysis for new and existing pumps. The system determines characteristic values and key performance indicators. There is no intervention in process control or direct contact between the sensor system and the conveyed fluid.

With key performance indicator-based condition monitoring, you detect and monitor operating statuses proactively. You can also optimize the overall output and robustness of your pump and pipe systems. This will increase the efficiency of your entire production plant. You can access the data conveniently via your corporate network. Or you use the LEWA cloud with extended analysis and service offers.


Advantages of LEWA Smart Monitoring:

  • Permanent monitoring of key performance indicators
  • Output of error states in plain text with exact error localization
  • Characteristic values for assessing the pipe system and conveyed fluid status
  • Historical data for operating analysis and profitability calculation based on pump efficiency
  • Data connection to the local control center via standard OPC UA interface
  • Connection to LEWA customer portal for additional services
  • Exclusive service offers for our Smart Monitoring customers

Diagnostics and Performance Metrics

The diagnostic dashboard.

With LEWA Smart Monitoring you have access to various diagnostic and performance parameters for your pump and the connected pipe system. This enables you to detect undesirable conditions in the process and the condition of the wear parts at an early stage using a simple traffic light system.

Technology and Operation Principle

How raw data becomes characteristic values:

Characteristic value determination is based on the recording of measured variables such as vibration, hydraulic pressure and angle of rotation. To get results, 2000 signals per pump head are processed per second. These signals are measured by the connected PLC.

Technical data

The output and transmission of the characteristic values and diagnostics is carried out via various interfaces:

The IPC has a web-based interface where settings can be made and the determined characteristic values and diagnostics are visualized. An OPC UA server is provided for transmission to a control center. In addition, characteristic values and diagnoses can be sent to the LEWA cloud and the LEWA customer portal via an Internet connection.
