At the centre of measuring pipe of V-cone flowmeter, there hanging a V-cone, via passing through the cone, liquid was speeded up and the static pressure was decreased and forms a low-pressure zone at the cone’s back, i.e. a throttle pressure△P was produced in the front of and at the back of the cone. According to Bernoulli equation and successional flux equation, acquires a volume flux equation of V-cone flowmeter.
