Power Supply Standard High Precision IP65 Flanged Metal Rotor Flow Meter
Metal tube flowmeter consists of measuring tube, 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 stream,especially suitable for mediums with low current velocity and low flow rate.Due to its excellent performance, reliability and competitive price, it is widely used in the fields of oil, chemical industry, steel manufacture, light industrial,water etc. Metal pipe flowmeter takes many different materials and is suitable for flowmeter measurement of all non-corrosive, corrosive and strong corrosive mediums.

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.
Workshop and Certificate
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
