"MT" series Rotameters are all Metal Variable Area Type Flow Meter designed to measure flow rate of liquids and gases under critical conditions. It consists of a tapered metal tube, an indicating assembly and float. A magnet encapsulated in float couples with rotating magnets connected to an indicating pointer as show in figure. Thus the movement of the float, is accurately indicated in terms of flowrate.

Orifice Plates are most commonly used primary elements for flow measurement in pipelines based on the principle of measurement of 'Differential Pressure' created when an obstruction is placed in the fluid flow, due to increase in fluid velocity. Orifice Plates cover a wide range of applications of fluid and operating conditions. They give an acceptable level of uncertainties at lowest cost and long life without regular maintenance.

Eureka Variable Area Flow Meters (Rotameters) work on the principle of Variable Area. The float moves freely up and down in thetapered borosilicate glasstube with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the floatweight are balanced in proportion to flow rate. The vertical position of the float as indicated by scale is the measure of theinstantaneousflow rate

Flow nozzle is a DP type flow meter consisting of rounded profile at inlet providing a smooth inlet to the fluid & the particles in the steam there by reducing the wear & tear thus extending the product life. This smooth inlet passage leads to lesser pressure drop & more efficiency. Eureka's NZL series is typically used for measurement of erosive & high velocity flow, such as high pressure high temperature steam. It can also be used with other fluids such as water, air or other gases.

Electromagnetic Flowmeters, Commonly known as Magmeters are a type of inferential flow metering devices used to measure the flow of electrically conductive liquid in closed pipe applications where the magnetic flux permeates the entire cross sectional area of the liquid flow. Magmeters measure electromotive force to determine liquid velocity using Faraday's Law of Electromagnetic Inducation and compute the flowrate using the equation of conductivity.

Eureka make Eumag Flowmeters operate with electrically conductive liquids and are relatively immune to the effects of Pressure, Temperature, Density & Viscosity of the liquid medium. For Eumag Flowmeter the electrically conductive liquid is defined as a liquid with a Conductivity of at least 5 Micro Siemens/Cm.

Principle of Vortex meter is based on the Karman vortex street. When fluid flows through a bluff body, vortices are alternately formed on both sides with opposite directions of rotation. These vortices each generate small amount of pressure. The pressure fluctuations are recorded by the sensor and converted to electrical pulses. The vortices develop very regularly within the permitted limits of the meter. Therefore, the frequency of vortex shedding is proportional to the volume flow.

Applications

Central lubricationTransformersCircular lubrication

The Weld Neck Flange is normally referred to as "High Hub" flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The pressure tappings are provided through the flange which are at a distance of 1" from the face of the plate. The Plate Holder Assembly is a combination of plate holder and an Orifice Plate designed for Ring Tongue Joint (RTJ) Flanges. The plate holder has a function of holding the Orifice Plate and also function as a gasket to prevent leakage of the process fluid. The plate holder has an oval or octagonal ring for mounting between ring type joint flanges. This metallic sealing system is useful for a fluid of high temperature and high pressure. The pressure tapping system normally is of the flange tap type.
