If you originally used an ultrasonic external clamp flow meter. Then change is very simple. Just need to remove the outer clamp sensor. Then install a new external clamp sensor. 2. If you originally used a sanitary electromagnetic flowmeter or a sanitary turbine flowmeter. Then it is recommended that you add a bypass pipe for the initial installation. In this way, when the beer flow meter needs to be replaced, the bypass pipe can be opened. Close the main pipe. Replace the beer flow meter in this way. Will not affect production efficiency.
