Magmeters – Magnetic Flow Meters

View sub products

Sika Sika Magnetic Flow Sensors for Conductive FluidsSika Magmeters are a range of electromagnetic flow meters that generate a magnetic field to measure flow level of conductive liquids.

Magnetic Inductive Flow Measurement

The range of magnetic flow meters consists of the VMI Magmeter, VMM Magmeter and VMZ magmeter. Each product has been designed for different applications and are available in various sizes for different pipes and systems. In addition, customer specific systems can be supplied to meet individual requirements.

The method of using electromagnetic measurement is time tested and has been deployed within process engineering for decades. Magmeters are extremely reliable as there are no moving parts to cause an obstruction and subsequent drop in pressure.

In addition, the method of using a magnetic field to measure flow levels is not affected by changes in viscosity, density, concentration or electrical conductivity. This results in a guaranteed level of consistent and accurate service .

Magnetic flow meters can be used and applied to almost any application and can be used to measure the flow of water, juices, pastes, acids, lyes and emulsions.

Magmeter Industries And Applications

The Principle Of Free Flow Operation

Magmeters operate according to the principle of induction. This means that the measuring pipe is contained within a magnetic field . If an electrically conductive fluid with the flow to be measured passes through the measuring pipe and thereby a right angle to the magnetic field, a voltage will be induced in the fluid.

The voltage level is proportional to the average flow level and is picked up by two measuring electrodes.

With regards to the flow proportional output signals there are two available –

  • Frequency output signal
  • Analog and frequency output signal

 

Smart flow magnetic sensors enable the flow measurement or dosing of conductive liquids without the use of any moving parts. This makes magmeters ideal for use when accuracy and product reliability are absolutely essential.
