Accurate steam flow measurement with Orifice Plate: Invertas, UAB implemented the decision Rietavas veterinary sanitation
Invertas, UAB, official Fuji Electric Premium partner In Lithuania, together with partners Axioma Service, successfully implemented a modern steam flow measurement project at Rietavos veterinary sanitation, UAB (Biovast) the company needed to replace an old, unreliable vortex flowmeter system and ensure accurate, stable and consistently measured steam flow even at five separate measurement points.
Selected solution – Orifice Plate Steam Flow Measurement – one of the most advanced and reliable methods for measuring steam flow in industrial environments. The project required extremely precise planning, as all installation and integration work had to be carried out in a very limited time, only after completely stopping production.
Why was it necessary to replace the old vortex flowmeter?
Rietavas veterinary sanitation has been facing a problem for a long time:
The old vortex flowmeter measured steam flow inaccurately, especially at low flow rates. Vortex technology has a clearly defined lower limit - if the flow rate is too low, the device simply stops recording data. This caused several serious problems:
distorted steam consumption data,
complicated control of technological processes,
incorrect energy metering,
it is impossible to realistically assess the downstream area,
risk of incorrectly managing production modes.
In addition, due to fluctuations in steam quality and possible condensate impurities vortex flowmeters may become even less stable — their measurements start to jump, which directly affects the overall optimization of production.
Under such conditions, the old system could no longer ensure sufficient accuracy, therefore, it became obvious that a more modern, reliable and steam-dynamics-adapted measurement solution was needed.
Since steam flow in a plant is constantly changing, accurate and consistent measurements are essential for process stability, targeted energy accounting, and financial efficiency.
Solution – Orifice Plate measurement technology with Fuji Electric sensors
Orifice Plate – It is a primary flow measurement element, the operation of which is based on a precisely determined pressure drop in a liquid or steam flow. When the steam passes through a specially designed orifice, a pressure difference is created that very accurately reflects the actual mass flow.
This method is perfect for steam due to several key advantages:
accurate measurements over the entire flow range, including very small flows,
stable operation under high pressure and temperature conditions,
there is no vortex type limitation, therefore downstream flows are measured accurately,
lower maintenance costs, because the structure is reliable and resistant to loads,
possibility of calculating the exact mass flow, using differential and absolute pressure sensors.
Fuji Electric in this field, it is characterized by highly reliable differential pressure sensors, renowned for their durability, vibration resistance and impeccable accuracy.
Invert, as a Fuji Electric Premium Partner, provided the complete sensor package:
differential pressure gauges,
absolute pressure sensors,
Orifice Plate elements specially adapted to the project,
technical recommendations for installation and configuration.
Project challenges: limited time and strict production shutdown condition
One of the biggest challenges of this project is very limited working hours. Since the operations of Rietavas Veterinary Sanitation (Biovast) are continuous, the replacement of measuring equipment was only possible after a complete stoppage of production. This meant:
just one short window of time,
very precisely planned work,
the need to synchronize multiple commands,
no possibility of delays or repetition of work,
all nodes had to be installed and started without errors.
Axioma Service performed professional installation:
dismantling of old equipment, manufacturing and installation of new Orifice Plate assemblies, pipeline preparation, sensor connection, system calibration and commissioning.
Despite the extremely tight schedule – everything went perfectly, and production was resumed on time.
Results: accurate measurements and increased process control efficiency
Immediately after launch, clear results were observed:
all five measurement points started to show stable and realistic steam flow,
downstream flows that the vortex flowmeter did not see are now measured accurately,
the data became consistent, without jerks,
production received reliable steam consumption accounting,
energy balance inaccuracies decreased,
overall process management efficiency has improved.
The UAB Biovast team remained particularly satisfied decision and noted that the system has been working flawlessly since day one.
Invertas, UAB – Professional partner for the supply and implementation of industrial solutions
In addition to the technical benefits, the project also demonstrated the importance of having a reliable partner throughout the implementation process.
