Vortex:

Vortex PhD and V-Bar flowmeters measure process fluids by detecting the frequency at which vortices are shed from an obstruction in the process fluid line (the bluff body). Piezoelectric sensors mounted outside the flow line acts as the transducer, converting vortex pulses into electrical signals. This is considered a "No moving parts" flowmetering technology. "Smart" electronics provide excellent noise immunity with provide a number of different electrical outputs proportional to the flow rate. These meters are available in two different styles. The first is an inline version, for line sizes 1" to 12", with a wide range of wetted materials. The second is an insertion version, for line sizes 3" to 80", and can be installed and removed without line shutdown. All the meters are designed for low and high pressure and temperature applications.

Turbine:

Turboline and Turbo-Bar flowmeters measure flow by generating an AC signal in direct response to the passage of the process fluid past the turbine blades. The blades rotate past a pick-up coil, the magnetic flux lines are broken and a small voltage pulse is generated. The turbine spins in direct proportion to flow. Because the turbine spins in proportion to the flow the measurements are extremely accurate. Electronics provide excellent noise immunity with provide a number of different electrical outputs proportional to the flow rate. These meters are available in two different styles. The first is an inline version, for line sizes ½" to 2 ½". The second is an insertion version, for line sizes 3" to 80", and can be installed and removed without line shutdown. All the meters are designed for low and high pressure and temperature applications.

Electromagnetic:

MAGFLO flowmeters employ Faraday's law to measure the volumetric flow rate of conductive liquids. These flowmeters offer important advantages over other technologies such as: no pressure drop, no moving parts, high accuracy and a wide variety of materials of construction. No maintenance, low cost of ownership, and high reliability make the electromagnetic flowmeter the flowmeter of choice for many flow measurement applications. Electronics provide a number of different electrical outputs proportional to the flow rate. These meters can be configured to measure flow in both directions. Meters are available in sizes from ½" to 80". Flanged and wafer style bodies and Tri-Clamp end connections.

Ultrasonic:

Sono-Trak is a non-invasive, transit-time ultrasonic flowmeter, which uses two transducers operating as both transmitter and receivers. The transducers are mounted on the outside of the process pipe, one upstream and one downstream. Each transducer generates a high frequency ultrasonic signal, which is transmitted through the pipe wall and into the fluid.Withboth transducers operating simultaneously, the fluid velocity determines the difference in transit time of the upstream and downstream signals. Advanced digital processing is used to accurately calculate the average flow rate. The meter can be programmed for Bi-directional flow with a number of different electronic outputs.

Positive Displacement Piston:

PDP flowmeters measure process fluid flow by utilizing four pistons driven by the flow of the fluid. The pistons drive a crankshaft through connecting rods in a fashion similar to a radial internal combustion engine. The rotational velocity of the crankshaft is directly proportional to the volumetric flow rate through the flowmeter. The crankshaft is equipped with a four-pole magnet element, which drives a magnetically coupled photo optic transmitter to provide the required output signal. Piston meters are designed for low flow and a wide range of viscosities. A number of different electronic outputs are available.

Positive Displacement Helix:

PDH flowmeters measure process fluid flow by utilizing two uniquely nested, counter rotating helical rotors as the measuring element. The rotors rotate in a synchronous fashion forming "moving pockets" of fluid, transporting the fluid through the flowmeter. The rotational velocity of the rotors is directly proportional to the number of transported pockets and, thus, the volumetric flow rate through the flowmeter. The flowmeter is equipped with a spur gear mounted on each rotor and a magnetic pickup coil. The rotation of the gear by the pickup breaks the magnetic flux, generating an AC pulse output directly proportional to the flow rate. Sizes range from 1 ½" to 12" for use in a wide liquid viscosity range. A number of different electrical outputs are available.
