The flow media are all neutral and aggressive fluid media which are free of solid particles, provided that the components coming into contact with the instrument are resistant in accordance with the ASV resistance list.
By connecting the oval wheel meter OVM to a SPS it can be used to dose fluids. No upstream or downstream sections are necessary. Dovetail sections moulded onto the metering tube allow for easy mounting of adjustable visual flow indicators, limit switches and a continuous readout transmitter. The scale prin- ted onto the metering tube is suited to the medium. The oval wheel meter has a compact design and is irrespective of the flow speed of the fluid as well as the fluid s density, temperature and viscosity. The GEM 850 flowmeter operates according to the variable area principle and has a transparent metering tube. In order to take the measurement, the rotation of the oval wheels is transferred by means of magnets to pulse tachometers. The GEMÜ 850 flowmeter operates according to the variable area principle and has a transparent metering tube. The viscosity of water at 20 ☌ is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). The oval wheels convey with each rotation four (isolated between the oval wheel and the measuring chamber) partial volumes through the meter. Viscosity is first and foremost a function of material. The oval wheel meter OVM is made up of a measuring chamber housing with two rotatable oval wheels with teeth which intermesh and rotate around and in opposite directions to one another. Rotating bobs are more common, rotating cups reduce the likelihood of vortex formation, and "cone and plate" viscometers create a constant shear rate at any speed.Oval wheel flow meter work according to the displacement principle and are used for the measuring, metering and monitoring of viscous fluid flow. Rotational viscometers use the concept of torque to measure the effort required to turn a disk or bob in a fluid.The GEM 3030 mFlow has two relay outputs, an. This can be done electronically for opaque fluids. The flowmeter works largely independently of the pressure, temperature, density and viscosity of the medium. Falling ball viscometers measure the time it takes for a sphere of a known size and density to descend through a stationary liquid.These meters use vibrating fork technology to provide reliable direct insertion measurement. You calculate viscosity by measuring the amount of time it takes for the liquid to move between two marks. Micro Motion Fork Viscosity Meters are accurate multi-variable devices that measure liquid viscosity, density and temperature under demanding conditions.
Liquid is drawn by suction into the upper bulb and allowed to flow down into the lower bulb.
