Choose the right and suitable energy measurement device for your application

The need for measurement is increasing. In addition to insight into energy consumption, more and more companies want insight into the load on their installation and into the quality of voltage and current (Power Quality solutions). In addition, they want to be notified in time if malfunctions occur.

Variety of energy meters

Fortop heeft een groot scala aan energiemeters in het assortiment. De verschillen zitten hem hoofdzakelijk in de bouwvorm, opties en type display. Een eenvoudige energiemeter kan op korte termijn voldoen, maar op langere termijn is een uitgebreidere energiemeter vaak snel terugverdiend.

The choice of an energy meter depends on what you want to measure and how you want the data to be presented.

Why measure power quality with an energy meter?

Power Quality problems are common but are not always visible. Unexplained failure of machine or installation raises many questions. In many cases there are problems with the quality of electrical energy (power quality). What Power Quality is exactly is described in our white paper Power Quality.

Insight into voltage dips with energy meter Janitza

View voltage dip with energy meter

You are in a room with the lights on. In a fraction of a second the light drops out briefly and comes on again immediately. Cause? A voltage dip. With an energy meter you have insight into voltage dips. We explain exactly what these voltage dips are in our white paper voltage dips
