We should all be asking ourselves whether we do enough to reduce nergy consumption in our homes and workplaces. This article discusses the most important elements of an industrial energy monitoring system in 2019. Read on to find out how to save money and the planet at the same time by reducing energy consumption in your plant.

Energy monitoring systems for IoT, IIoT, and Industry 4.0

There has been a lot of buzz around IoT, IIoT and Industry 4.0 in recent years. Fortunately, vendors want to make money, so they act instead of just talking. Some companies provide remote solutions, where their experts analyze data and send relevant reports.

Others offer platforms with clear dashboards to help you develop their own reports and insights. These solutions tackle issues such as energy monitoring system, process improvement, and condition monitoring with a variety of methods.

Some energy monitoring systems use control systems to monitor and analyze the process energy, and others use gateways to send data to the cloud or platform, bypassing the control system altogether.

As with anything, these systems have their pros and cons. With remote access, we can focus on the data related to the specific application, instead of being overwhelmed by irrelevant information. Plus, we can limit access to reduce security issues.

If you are interested in industrial energy management systems in general (energy monitoring is just one part of this field), take a look at our energy monitoring system instrumentation guide.

Top industrial energy monitoring devices

To give you a headstart in industrial energy monitoring, we have compiled a list of devices that have proven themselves in many industrial energy monitoring setups. Some of these devices are specifically built for energy monitoring while others have more uses but are better suited to energy monitoring than their peers. All of them are relatively easy to install and supply a lot of data.

Endress + Hauser Proline Prowirl F 200

This smart device from Endress + Hauser brings a lot of benefits for the end user. It has integrated temperature and pressure sensors for mass and energy flow of saturated and superheated steam. Plus, this can withstand temperature shocks, water hammers, and heavy vibration.

We can also get wet steam detection and measurement, which gives us the key to controlling the steam efficiency of the entire plant.

The Prowirl Vortex Flowmeter can also calculate the chemical properties (gross calorific value, net calorific value) of natural gases. The calculations are based on time-tested standard calculation methods. It is
possible to automatically compensate for the effect of pressure and temperature via an integrated sensor or constant value.
This makes it possible to output the energy flow, standard volume flow and mass flow in accordance with several standard methods, for example:

  • AGA5
  •  ISO 6976
  • GPA 2172

Omnigrad TR 10

The Omnigrad M TR10 from Endress+Hauser is an optional head transmitter. Together with all common communication protocols, it makes the device ready to use with enhanced measurement accuracy and reliability compared to directly wired sensors.

PT 100 with GDM connector and 4…20 mA output

The PT 100 with GDM connector and 4…20 mA output is a compact temperature transmitter for measurement of liquid and gases from BB Sensors.

This can be used in engines and compressors, plant and ship construction and mechanical engineering sectors. Also, the pt100 screw in sensor with Hirschmann plug and output signal 4-20mA offers high reliability and easy-to-clean surfaces.

Memograph RSG 45

The Memograph M RSG45 Advanced Data Manager from Endress+Hauser is a flexible and powerful system for organizing process values. Memograph M adapts quickly and easily to any application and supports remote monitoring.

Connecting all the devices above to the RSG45, you can have a high-class energy monitoring system. This advanced data manager ordered with the option energy software package offers 4 calculation options for water and steam applications using the input variables flow, pressure, temperature (or temperature differential):

  • Energy calculation
  • Mass calculation
  • Density calculation
  • Enthalpy calculation

An energy monitoring system monitors, controls, and optimizes energy performance in a plant. That means it measures the generation, transmission, and consumption of energy. It should also help diagnose problems like over-consumption and leaks across the entire plant. Using these devices will allow us to reduce energy consumption.
