Flow Meter Valve, Flow Measurement Itrument, Chemical Flowmeter Valve
K Series Mass Flowmeter (hereafter we call K) is designed according to the Coriolis Principle.It has been widely for the process detecting and custody transfer/ﬁscal unit in many industries such as petroleum, petroleum and chemical,chemical industry, pharmacy, paper making, food and energy, and so on. As a fairly advanced kind of ﬂow measurement instrument, it has been paid attention by the circle of measure- ment measurement and accepted by many customers home and abroad.
K is designed according to the principle of Coriolis force.Under the
alternating current eﬀect, the magnet and coil installed on the measuring tube will make two parallel measuring tubes vibrate according to some ﬁxed frequency. Once there is ﬂow passing through the pipes, Coriolis force will give rise to deﬂection (phase shift) on the vibration of two pipes and the deﬂection of vibration is directly proportional to the mass ﬂow of ﬂuid. Pick up them and the mass ﬂowrate could be calculated.
The vibration frequency of measuring tube is determined by the total mass of measuring tube and inner ﬂuid. When the ﬂuid density changes, the vibration frequency of measuring tube will be also changing, as a result, the ﬂuid density can be calculated.
The temperature sensor installed in the pipeline can pick up the ﬂuid temperature on time under the coordination of measuring circuit.
Comparing with the traditional ﬂow measurement method, K has following obvious merits:1.3.1. Enable to measure directly mass ﬂow rate of ﬂuid in the pipeline without changing any parameters, which avoids the some measurement error of intermediate links. Its mass ﬂowrate can be high accuracy and good repeatability within bigger range of turndown ratio.
1.3.2.Fluid measured can be more extensive, such as the steady uniform ﬂow of common viscosity ﬂuid, the high viscosity ﬂuid, non-Newtonian ﬂuid, slurry containing some solid components and the liquid containing some trace of gas.
1.3.3.Due to the small vibration, measuring tube of the K can be regards as non- moving parts, which will reduce the maintenance of ﬂowmeter, enhance the stability and lifetime.
1.3.4.Besides the mass ﬂow measurement, the density and temperature and even consistency can also be picked up and output.
