Adhesives and Resins
Litre Meter specialise in the design, manufacture and supply of flowmeters. The VFF meter has been developed for 30 years and provides measurement ability over wide ranges and, if needed, at extreme pressures. Listed below are all the flow meters within our range that are suitable for adhesives, epoxy resins and similar:
Fluids and gasses all have different characteristics, which is why certain flow meters are better for specific materials. They all vary in given pressure, temperature, density, conductivity, and composition, meaning the best way to measure them can also vary.
We have a selection of flow meters that are suitable for measuring the flow of adhesives and resins, all of which avoid the problems that can arise due to its viscous and sticky consistency to ensure an accurate reading.
The following flow meters are designed for a range of materials, many of which with a high viscosity:
Rotary Piston Meter
One of the most common choices when it comes to measuring the rate of high viscosity materials, the rotary piston meter uses an oscillating piston for consistent accuracy and efficiency.
Also known as a positive displacement flow meter, a rotary piston meter measures the volume of a fluid by counting known fixed volumes repeatedly, using compartments which turn with the oscillating piston.
Each compartment contains an exact volume, which makes it easy to monitor and measure amounts, and avoid the sticky texture. The more fluid flowing, the faster the meter turns.
The Pelton wheel works by using a large blade area with ferrites and a sensing coil to measure and monitor the flow rate of all kinds of liquids.
Its large blades mean that it is ideal for jobs that need to monitor and measure very low flows, just like adhesives and resins.
As the flow enters the meter, the rotor begins to turn at a speed that is proportionate to the flow rate, and the small sensing coil detects the ferrites of each tip of the rotor blades as they pass. Itís because of this movement that the Pelton Wheel is also known as a radial turbine.
Used to calculate the average velocity of fluids, turbine flow meters utilise a vaned rotor that makes an accurate measurement as the fluid travels through.
The vaned rotor is found inside the meter; itís centred on a shaft and rotates on bearings. To improve the accuracy of readings, you will also find a shaft inside a turbine flow meter, which is supported by tube bundles which provide a degree of flow conditioning for the fluid.
This model is well known for its excellent precision, as well as the diverse range of materials it can perform for.
The movement of a helical screw is controlled by the fluid; as the fluid flows through it, the meterís screws and gears are forced to rotate.
With two, normally identical, counter rotating gears that form a continuous and constant volume cavity, itís possible to determine the flow rate per revolution.
Helical screw flow meters work well for high viscosity fluids like adhesives or resins due to the fact that very little force is needed to rotate the gears.
Digmesa is well-known for their flow rate measurement and dispenser devices for liquids, as well as their consistency of high-quality products.
So many industries rely on flow measurement, and the Digmesa range of technologies has flow meters to suit various materials; some ideally suited for low pressure adhesive flow measurement and others for higher viscosity adhesives.
Their range provides high precision measurements to ensure accuracy in whatever job the flow meter is used for. Contact factory for details.
