Flow measurement without inlet and outlet runs
The water flow of Porvoon Energia’s new district heating battery is measured with Endress+Hauser’s Full Bore flowmeters
Porvoon Energia invested in a district heating battery that reduces the use of peak load plants and balances heating distribution during downtime. Endress+Hauser provided the plant with flowmeters that utilize cutting-edge technology.

Porvoon Energia needed a solution for two-way flow measurement with minimal space requirements for a district heating battery.
-
Full Bore 0 x DN flowmeters do not require traditional inlet and outlet runs.

The Full Bore flowmeters, launched in 2019, provided space and cost savings during the construction phase and will guarantee reliable measurements throughout the plants' lifecycle.
“One of the aims in the planning stage of the Kipinätie facility was to minimize the inlet and outlet runs required by conventional measurement technologies. Endress+Hauser’s 0 x DN Full Bore flowmeters use multiple electrodes to provide reliable measurements that are independent of flow profiles – without traditional inlet and outlet runs,” Endress+Hauser’s Product Manager Ari Kettunen says.
The district heating battery’s flowmeters are used to measure water flow in both directions – depending on whether the battery is being discharged or charged. Luckily, Full Bore flowmeters provide two-way measurement data, the accuracy of which, according to Porvoon Energia's Automation Manager Marko Heikkilä, has been positively surprising with small water flows as well.
“Since the district heating network is sensitive to variations in differential pressure, the choice of flowmeter was given particular attention. The flowmeter has 0–700 cubic meters of water flowing through it per hour, and even the slightest imbalance in the battery’s input and return flows is immediately visible in the district heating pumping of main production plants. The repeatability of the measurement must be top-notch. So far the Full Bore has provided just that,” praises Heikkilä.
