Prior to the Bronkhorst solution, the fish farmer used variable area flow meters (VA meters) in combination with manual needle valves at the site. To comply with the automation and remotely control requests of the customers, the pilot setup was executed with FLOW-BUS communication protocol. To be able to customise temperature and pressure reading, the final setup was executed with Modbus. Due to the digital electronics on the MASS-STREAM devices, it was possible to upgrade the firmware with Modbus.
An important reason for the customer to use the MASS-STREAM flow controllers is their good price-performance ratio. As the company needed multiple instruments for this application, this was an important aspect. Moreover, the integrated display on each of the devices allows to locally override the remote settings, if needed. On top of that, the robust design with direct through-flow measurement based on the Constant Temperature Anemometer (CTA) principle is favourable in the demanding Norwegian surroundings.
Fish lice in a fishing farm can have a devastating effect for a farming company. As fish lice treatment is very expensive and time consuming, preventing the occurrence of fish lice by means as aeration is extremely cost reducing.
