Rosemount 8800 Weld-end vortex flow meter Flange gaskets are eliminated by welding the flow meter directly into your process piping The only vortex flow meter available with zero potential leak points Ideal for applications where reducing potential leak points is important Available with ½ inch through 12 inch 15 mm through 300 mm line sizes. They are mainly used in semicon ductor commercial HVAC landscape. Therefore the frequency of vortex shedding is proportional to the volume flow.

The Model M22 M23 M24 and M24R Pro-VTM Multivariable Mass Vortex Flow-meters standard temperature option ST process temperature range is -40C to 260C. 1 The vortex flow meter is based on the well-known Where ST is the Strouhal number v the fluid von Karman vortex street phenomenon. 1 Differential pressure flowmeter.

Rosemount 8800D Vortex Flow Meter Standard or MTA HART Protocol 7 Rosemount 8800D Series Vortex Flow Meter Read this manual before working with the product. The split type flow meter is used in a humid environment or a place with high temperature. SDVT serials vortex street flow transducers detect the output frequency by using.

Applications in the chemicals and petrochemicals industries for example in power generation and heat-supply systems involve widely differing fluids. The Vortex is a precision measuring instrument and should be handled carefully. Upon receipt examine your meter for visible damage.

The outputs include 4-20 mA and pulse for flow rate as well as high and low alarms. Principle of measurement FV4000 1 Solid body 2 Piezo sensor The frequency of vortex shedding is proportional to the flow velocity f v and inversely proportional to the width of the solid body d. The longest transmission distance between the signal converter and the sensor is 10 meters and the connecting cable is a 2-core shielded cable.

This velocity and d is the bluff body diameter. The output frequency is directly proportional to the flow velocity so a velocity v is derivable by using a tested frequency f. Liquid 12 62 to 200 - 2000 m3h GasSteam 5 25 to 1380 - 11000 m3h Ambient Temperature.

The Hydro-Flow Series is a series of low-cost vortex meters designed for water measurement. The Rosemount 8800D Vortex Flowmeter consists of a meter body and transmitter and measures volumetric flow rate by detecting the vortices created by a fluid passing by the shedder bar. Vortex Flow Meters are typically made of 316 or Hastelloy stainless steel and include a cliff body vortex sensor assembly and transmitter electronics although the latter can also be installed remotely.
