Transit ultrasonic clamp-on flow meters measure flow using ultrasonic wave travel time. One wave is sent from an upstream to the downstream transducer, and another wave is sent from the downstream to the upstream transducer. The difference between the two travel times is used to calculate flow velocity.

Doppler clamp-on flow meters utilize the Doppler Effect to measure fluid flow. These work by transmitting ultrasonic waves into the fluid, which are then reflected to the sensor by particles or bubbles in the flowing fluid. The frequency change between the transmitted and received waves is used to calculate the flow velocity.

Product Details:

Open Channel flow meters measure level, flow rate and total volume of water flowing through weirs, flumes, channels and partially filled pipes. The flow meters use a non-contact level sensor to detect the water level and then calculate the flow rate and volume using the Manning equation and characteristics of the channel.
Open channel flow monitoring is a method of determining liquid volumetric flow rates in applications that rely on moving liquids through open conduits rather than enclosed full pipes. Examples of these types of applications include wastewater processing effluent flows, managing water usage in agricultural irrigation channels, and monitoring flows through storm water systems. Traditionally, this type of measurement has been performed via the use of flumes or weirs in conjunction with a liquid level ultrasonic sensor. In recent years, global environmental concerns and increased scarcity of freshwater resources has necessitated more accurate, reliable and cost effective methods of Open Channel Flow Measurement. Two such improved methods offered by SmartMeasurement include the advanced transit time ultrasonic Area-Velocity measurement technique and the low-cost Doppler flow meter ultrasonic technology.

Product Details:

An ultrasonic flow meter measures the flow of a liquid or gas by sending ultrasonic waves across a pipe, containing the flow in the direction of the flow and in the opposite direction of the flow. The ultrasonic waves and the velocity of the flow of the liquid or gas can be combined to determine the flow rate.

Thermal mass flow meters are used in the monitoring and/or controlling of mass-related processes – such as chemical reactions – that depend on the relative masses of unreacted ingredients. In detecting the mass flow of compressible vapors and gases, the measurement is unaffected by changes in pressure and/or temperature. One of the capabilities of thermal mass flow meters is to accurately measure low gas flow rates or low gas velocities (under 25 ft. per minute) – much lower than can be detected with any other device

Mass flow measurement differs from volumetric measurement in that volumetric measurements are affected by all ambient and process conditions that influence unit volume or indirectly affect pressure drop, while mass flow measurement is unaffected by changes in viscosity, density, temperature, or pressure.

Product Details:

A Steam flow meter primarily consists of a bluff body, a sensor assembly and a transmitter. A bluff body or a shedder is nothing but a non-streamlined object or a barrier placed perpendicular to the axis of the pipeline, around which the medium flows. The frequency of the vortices, i.e. the number of vortices shed per second, is directly proportional to the velocity of the medium. This vortex shedding frequency is used to calculate the mass flow. The sensor assembly records the pressure and velocity oscillations generated on each side of the bluff body by the vortices and generates a digital linear output signal

Electromagnetic flow meters (or mag meters) are a type of velocity or volumetric flow meter that operates pursuant to Faraday's law of electromagnetic induction – which states that a voltage will be induced when a conductor moves through a magnetic field. Magmeters can detect the flow rate of conductive fluids only.

 

Electromagnetic Flow Meters, simply known as mag flow meter is a volumetric flow meter that is ideally used for wastewater applications and other applications that experience low-pressure drop and with appropriate liquid conductivity required. The device doesn’t have any moving parts and cannot work with hydrocarbons and distilled water. Mag flow meters are also easy to maintain. Magnetic flow meters work based on Faraday’s Law of Electromagnetic Induction. According to this principle, when a conductive medium passes through a magnetic field B, a voltage E is generated which is proportional to the velocity v of the medium, the density of the magnetic field, and the length of the conductor.

A Coriolis mass flow meter is a highly accurate device used to measure the mass flow rate of fluids flowing through a pipe. It operates based on the Coriolis effect, where fluids passing through a vibrating tube cause it to twist or oscillate. This twisting is directly proportional to the mass flow rate of the fluid.
