It is usually the flow rate per hour; there are countless manufacturers that produce such meters, so it’s necessary to check the nameplate and the manufacturer’s model specifications
What is displayed is the instantaneous flow rate; whether it is per minute or per hour depends on the settings specified. This is a secondary meter, and many manufacturers in China produce them at reasonable prices. The price varies depending on the number of channels required, whether any additional functions are needed, the precision requirements, and if the meter is to be used in a hazardous environment, in which case the explosion-proof rating also plays a role. Different requirements result in different prices.
I finally figured it out; this is a flow meter produced by Yudian Company.
