VARIABLE AREA FLOWMETER
Metal pipe flowmeter consists of measuring pipe, float, indicator and process connection components with the characteristics of small size, wide measuring range, easy installation. In the industry area, it is widely used to measure flow of gas, liquid, and steam, especially suitable for mediums with low current velocity and low flow rate.
Product features
1.Single axle, smart display, high reliability, easy maintenance, long life time.
2.Less requirement on the tube.
3.Flow ratio:10:1, special type: 20:1.
4.Suitable for measurements of mediums with small pipe and low flow rate.
5.LCD display, displaying instantaneous flow and whole flow at same time.
6.Non-contacting magnetic coupling transmission.
7.Metal structure, suitable for strong corrosive mediums and environments with high temperature, high pressure and flammable and explosive conditions.
8.Two-wire available, battery and AC supply to choose.
9.Multiple parameters calibration function, data restoration and back-up, power-fail protection function.

In order to prevent the rotor from touching the wall when moving up and down the center line of the tapered tube, two methods are usually used: one is to install a guide mandrel in the center of the rotor to keep the rotor on the center line of the tapered tube. Moving up and down, the other is that there is a chute on the edge of the rotor disc. When the fluid flows through the rotor from bottom to top, it will bypass the rotor on the one side and generate a reverse thrust through the chute at the same time, so that the rotor will not rotate around the centerline. When it stops rotating, it can keep the rotor from hitting the tube wall during working. The rotor material of the rotameter can be made of stainless steel, aluminum, bronze, etc.

FAQ
Q: The new magnetic flap liquid level gauge can't show liquid level?
A: 1.check whether there is block in by pass pipe 2.check the the density of medium 3.check whether the float ball is stucked by float ball.
Q: The longest length of magnetic flap liquide level gauge?
A: the length is customized,but in order to be convenient for transport,if the length is over 6m,we recommend
Q: If the float ball is installed at the wrong opposite direction,what's the influence?
A: reading level will be higher than true level,usually higher by length of floatball-70mm
Q: What's installation details of magnetic flap liquid level gauge ?
A: 1.before installation,check specification with label plate. 2.There shouldn't magnetic field within 400m
Q: There is problem in output signal 4--20mA?
A: 1.Check working power supply 2.check wiring 3,check load resistance 4.verify measuring range,zero point
Q: what's specification we need to know before purchasing magnetic flap liquid level gauge?
A: medium density,working temperature,working pressure,material,flange center to center distance,flange standard,whether need 4--20mA output signal;wether need level alarm
