Flow

Each flowmeter can be configured from a variety of chemically compatible alloys such as, Quartz, Hastelloy, Monel, Titanium, Tantalum, Inconel, and Stainless Steel. The unique design of these sensors creates an unobstructed path for liquid flow, so nothing makes contact with the fluid except the wall of the tube. Solids in the fluid flow cannot harm the sensor. A variety of standard or custom process connections are available, such as NPT, Tri-Clover, Flanges, or Tube Stubs to best adapt to your existing equipment.

You can also choose electropolished sensors that can be used to measure ultrahigh purity gases. These inline gas flow meters are often used on small lines (1″ or smaller) with flow rates ranging from 25 SCFM to a few hundred SCFM.

They are suited for use with most non-condensing gases, even explosive and corrosive gases. For areas where little or no straight run is available, the RheoVac™ flow conditioner and its unique honeycomb design works to eliminate measurement errors that routinely confound ordinary sensors. A variety of standard or custom process connections are available, such as NPT, Tri-Clover, or Flanges to best adapt to your existing equipment.

Each of our flow switches has an adjustable set point—a minimum or maximum flow rate—and once the measured fluid reaches this point, the device transmits a trip signal to another device (such as a pump) that modifies the rate of flow. Flow switches are often used as a lower cost alternative to a flow meter for measuring flow if all that is needed is indication of flow beyond (above or below) a particular value.

The electronics transmitter provides these outputs to your control system over analog 4-20mA, Modbus or OPC protocols. The RheoVac probe is ideal for power plant condenser performance monitoring as well as industrial drying, evaporation monitoring, vacuum pump capacity monitoring and more.

These flow meters are optimized for accuracy and reliability using turbine, oval gear, ultrasonic, and nutating disc technologies.

EPI offers gas measurement solutions for your high temperature (XT), high purity (PURE), and large duct (MultiGEN) applications. Additionally, the VAL series provides a more economical solution while maintaining the high standards that EPI has set for accuracy and reliability.

GEN meters are certified for use in ordinary locations (non-hazardous) and CSA/Cus Class 2252-03 & 2252-80 approved instruments. Assembled with stainless steel wetted materials (optional Hastelloy C-276®) the GEN series is available in both inline and insertion configurations.

This extensive product range includes industrial and dial thermometers (and matching thermowells) as well as high-quality manometers, and an extensive range of force sensors and load cells.

Vortex flow meters measure fluid velocity using a principle of operation referred to as the von Kármán effect. It states that when flow passes by an obstruction in the flow path, vortices are generated in a repeating pattern.

In a vortex flow meter, this obstruction is referred to as a bluff body. The bluff body causes the process fluid to separate and form areas of alternating differential pressure known as vortices around the backside of the bluff body. In Pro-V vortex flowmeters, a sensitive piezoelectric crystal sensor detects these vortices. The frequency at which the vortices are shed is directly proportional to the flow velocity. With the fluid velocity and area of the pipe known, a volumetric flow rate is calculated.

With optional integrated temperature and pressure sensors, Pro-V vortex flowmeters can provide a compensated mass flow rate. With the energy monitoring option, Pro-V meters can also provide a reliable (BTU) energy measurement of water, thermal oils, and steam. Insertion style vortex flowmeters are a more economical option on large line sizes and can be installed under full process conditions (hot tapping).

Pro-V® multivariable flowmeters utilize three primary sensing elements – a vortex shedding velocity sensor, an RTD temperature sensor, and a solid-state pressure transducer – to measure the mass flow rate of gases, liquids and steam.

Systems that use external process measurements to calculate mass flow may not provide adequate compensation for the fact that process conditions can change radically between the point of velocity measurement and the point where upstream or downstream pressure and temperature measurements are being made. Because the Pro-V multivariable flowmeter measures all of these parameters in a single location, it delivers a more accurate process measurement.

Integrating multivariable output capability with a single line penetration also simplifies system complexity and helps reduce initial equipment cost, installation cost and maintenance costs.

Most Chemical and Petrochemical Industry processes run continuously in harsh environments: abrasive process slurries, corrosive chemicals, high process temperatures, poor steam quality, and other factors can damage instruments, leading to process downtime and increased production costs. Azbil’s Chemical and Petrochemical industrial automation solutions provide peace of mind when measuring and controlling pressure, level, flow, and temperature.

Water Optimized Vane / Piston Style FlowMeter: Variable area flowmeters measure flow by allowing the flow stream to change the opening within the flowmeter by moving an internal part. When the flow increases, the fluid generates more force and moves the internal part farther.

Variable Area (Float Style): Spring-opposed float designs allow this type of flowmeter to be installed in horizontal pipes because the functioning of the float is not dependent upon gravity. These flowmeters can be read locally because their glass or plastic metering tubes have markings that relate the height of the float (that can be seen) with the flow rate of the fluid. 

Laminar Flow Element Flowmeter: Laminar flow elements, present a special case wherein the fluids are in a laminar regime (low Reynolds number) and the pressure drop is linear in relation to the flow rate. That makes it very useful for reading the low end of the scale and increases the “turn down” from the usual 10:1 to 100:1. This technology is optimal for clean gas flows.

Thermal Flowmeter for Compressed Air: In a typical thermal flowmeter, a measured amount of heat is applied to the heater of the sensor. Some of this heat is lost to the flowing fluid. As flow increases, more heat is lost. The amount of heat lost is sensed using temperature measurement(s) in the sensor. 

Paddle Wheel Flowmeter: Paddlewheel flowmeters use the mechanical energy of the fluid to rotate a paddlewheel in the flow stream. When the fluid moves faster, the paddlewheel spins proportionally faster. Shaft rotation can be sensed mechanically or by detecting the movement of the paddles. 

Coriolis Mass Flowmeter: Coriolis mass flowmeters measure the force resulting from the acceleration caused by mass moving toward (or away from) a center of rotation. In a Coriolis mass flowmeter, the “swinging” is generated by vibrating the tube(s) in which the fluid flows. The amount of twist is proportional to the mass flow rate of fluid passing through the tube(s). 

Magnetic Flowmeter: Magnetic flowmeters use Faraday’s Law of Electromagnetic Induction to determine the flow of liquid in a pipe. In a magnetic flowmeter, a magnetic field is generated and channeled into the liquid flowing through the pipe. Following Faraday’s Law, the flow of a conductive liquid through the magnetic field will cause a voltage signal to be sensed by electrodes located on the flow tube walls. When the fluid moves faster, more voltage is generated. Faraday’s Law states that the voltage generated is proportional to the movement of the flowing liquid.

Positive Displacement Flowmeter: Positive displacement is the only flow measurement technology that directly measures the volume of the fluid passing through the flowmeter. Positive displacement flowmeters achieve this by repeatedly entrapping fluid in order to measure its flow. 

Turbine Flowmeter: Turbine flowmeters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream. Blades on the rotor are angled to transform energy from the flow stream into rotational energy. The rotor shaft spins on bearings. When the fluid moves faster, the rotor spins proportionally faster.

Differential Pressure Flowmeter: Differential pressure flowmeters use Bernoulli’s equation to measure the flow of fluid in a pipe. Differential pressure flowmeters introduce a constriction in the pipe that creates a pressure drop across the flowmeter. When the flow increases, more pressure drop is created. Impulse piping routes the upstream and downstream pressures of the flowmeter to the transmitter that measures the differential pressure to determine the fluid flow.
