Mass flowmeter Introduction:
HNKF-9000 Coriolis mass flowmeter Coriolis mass flowmeter is based on (Coriolis Force) principle, direct precision measurement of fluid mass flow rate, without any pressure, temperature, viscosity, density conversion or correction. The structure is composed of two parts, the sensor unit and the transmitter unit. Meter according to the national standard design and manufacturing, explosion-proof mark is intrinsically safe (Ex) ibIIBT2-5? Coriolis mass flowmeters directly measure the mass of the fluid, with high precision (0.1% to 0.2%), the scope of application Canton (measure a variety of non-Newtonian fluids, various slurries, suspensions, high viscosity fluids, etc.), and low installation requirements (before and after the meter straight pipe do not ask), reliable, stable, low maintenance features .
Application: mud and sludge, and various oils, fats, dyes, suspensions, chocolate milk, cream, various alkali salt flow measurement
HNKF-9000 Coriolis mass flowmeter
First, the measuring principle:
HNKF-9000 Coriolis mass flowmeter based on the Coriolis mass flow rate of fluid mechanics, when the fluid linear motion and rotation occur simultaneously there Coriolis force generation. When the two conditions are met: (1) dual elbow with some frequency vibration, (2) fluid flow in the pipeline, it will produce a new force - the Coriolis force, which is composed of pipes and pipe vibration additional force generated by the fluid flow synthesis, this force produces torque on the elbow, so that its center line elbow symmetrical torsion. Both sides of the elbow by a displacement sensor to detect the electrical signal, and then the electric signal is processed, derived directly mass flow.
FC = 2 × △ m (ω × v)
FC = Coriolis force
△ m = mass of fluid motion
ω = angular velocity
v = radial velocity (rotation or vibration when)
