OVAL supplies energy-saving
sensors for overall utilities.
“To know the amount of energy currently in use” +“To confirm the amount of reduction”
How much is energy ﬂuid
currently in use?

How much is the eﬀect byworking on energy saving?

Is waste present or not?

Installation of flowmeters is required.
For continuous energy-saving activities, it is essential to control (measure) the energy usage throughtemperature, pressure, and flow measurement. "Visualizing" the amount of saved energy and appreciating those who engaged in such activities are the keys to successful energy-saving activities.
OVAL provides various flow sensors to cover all energy flow measurement needs from main pipes tobranch pipes at inexpensive. Our hope is to help users in setting energy-saving targets and controlling
specific energy consumptions by visualizing the flows of energy fluids.
