2 RVL Series Liquid Meter The RVL series meter utilizes vortex-shedding technology to provide a repeatable flow measurement accurate to ±% of full scale. The meter has no moving parts, and any potential for fluid contamination is eliminated by the meter's corrosion-resistant all plastic construction. The meter includes a compact -wire (4-0 m) or -wire (0-5 Vdc or pulse) transmitter, contained within a conveniently replaceable plug-in electronics module. ll electronics are housed in a corrosion-resistant enclosure. Unlike meters containing metal or moving parts, the RVL is perfect for aggressive or easily contaminated fluids. pplications range from ultra-pure water to highly corrosive chemicals and slurries. Units may be re-calibrated and the meter output span reprogrammed in the field. Operating Principle Software Utility (Optional) n optional software utility kit is available to configure the RVL 4-0 m or 0-5 Vdc outputs. (The pulse output is not field configurable.) Part number RVS0-954 contains a RS 9-pin cable, software, TTL to RS converter and a board interface cable. The program enables easy configuration of span, damping and units of measurement. Operation of the RVL vortex flow meter is based on the vortex shedding principle. s fluid moves around a body, vortices (eddies) are formed and move downstream. They form alternately, from one side to the other, causing pressure fluctuations. These are sensed by a piezoelectric crystal in the sensor tube, and are converted to a 4-0 m, 0-5 Vdc or pulse signal. The frequency of the vortices is directly proportional to the flow rate. This results in extremely accurate and repeatable measurements using no moving parts. Material Selection When choosing the best flow meter for a process, it is necessary to review the fluid to be measured, its concentration, the minimum and maximum operating temperatures, operating pressure, fluid viscosity, suspended particles, density of the fluid and, most importantly, expected flow range. One advantage of utilizing a RVL vortex flow meter is that there are no gaskets or elastomers in the meter. Therefore, one need only be concerned with the thermoplastic material used in body construction. In a thermoplastic piping system, the material chosen for the flow meter should match that of the pipe wherever possible. hemical ompatibility - Excellent - Good - Fair - Severe effect ompatibility hemical PV PVF PV Polypropylene luminum Hydroxide hlorine Water Fuel Oils Hydraulic Oil Hydrochloric cid 7% Hydrofluoric cid 0% Isopropyl lcohol Nitric cid (oncentrated) Phosphoric cid (>40%) Potassium Hydroxide Propylene Glycol Sulfuric cid (0-75%) N/ N/ N/ N/ Line Fluids Many factors may affect the capability of a meter to measure the flow of specific fluids accurately. ifferent solutions have varying effects on meters. For instance, heavy particle suspension will wear down internal parts on some meters or cause sensing inaccuracies for non-obtrusive metering systems. For vortex flow meters, high viscosities tend to dampen the formation of vortices and reduce the effective range. Particles and internal bubbles do not usually affect vortex meters. PVF models typically work very well in slurry services, though slurries containing grit can wear down the bluff body over a period of time. lso, long fibers can catch and build up on the bluff, decreasing accuracy. Standard factory calibration is for tap water at SSU ( cst) viscosity and ambient temperature. Viscosity above cst will raise the minimum readable flow rate, reducing rangeability. The effect is linear to viscosity. No adjustments are required for specific gravities up to.0. Liquids with high specific gravities will adversely affect the permissible amount and duration of overrange flow.
