It has gone through two development stages of pneumatic and electric meters. It is mainly used to measure the flow of high viscosity and low Reynolds number fluids. The target flowmeter has been used in industrial flow measurement since the 1960s. Target flowmeter For High Viscosity Liquids Measurement More moving parts needs maintenance compared ,it can be destroyed by flow surges and gas slugsģ). Not good for the multi-phase fluids flow measurement such as used as Refrigerant flow meter. Relatively high price cost for large gear flow meter sizes for stainless steel material. The flow meter is really bully and heavy, increase a lot shipping charges when delivery Poor choice for medium for water, because the carbon steel wet material can rusty, also an increase in fluid slippage. *Disadvantages of Oval Gear Meter for high viscosity flow meter Simple to install, no straight pipeline needed, and the meter can be mounted in restricted areas. Lower Price cost with carbon steel material than Coriolis flow meter price It can work without external power, just mechanical register to display instant flow and total flow, now currently Silver Automation Instruments develops gear flow meter with transmitters which has pulse or 4-20mA,HART,RS485 communication. High accuracy results over a wide range of viscosities and can measure fluids with viscosity max 2,000 cp. *Advantages of Oval Gear Meter for high viscosity flow meter It is designed primarily for use with higher-viscosity fluids, for flow metering of oils, petrol, diesel, syrups and fuels. Oval Gear Meter For High Viscosity Liquids MeasurementĪdvantage of Oval gear flow meter for high viscosity fluid Pressure drop that rise sharply with viscosityĢ). *Disadvantage for Coriolis mass flow meterĬannot be used to measure strong corrosive mediumĬannot measure low density gas flow rate. Not demand flow conditioning, not straight pipelines request when installation. *Advantages of coriolis meter for high viscosity flow meter Our Coriolis meter now has many successful applications when measuring bitumen, molasses, Heavy crude oil flow rate and so on.ĭirect mass flow and density, temperature measurements by only one sensor. High viscosity flow meter coriolis meterĪdvantage for Coriolis Meter for high Viscosity FluidĬurrently the max flow viscosity we measure by Coriolis meter is 500,000 cp. Lots of different type flow meters cannot measure high viscosity fluid.ġ). When a flowmeter application involves the use of high viscosity liquid, the customer should pay attention to select an appropriate meter. It is a kind of high viscous medium, and we often use positive displacement flow meter ( oval gear flow meter ) or coriolis mass flow meter to measure resin flow rate. This resin oil is a common name for white alcohol, mainly aliphatic hydrocarbons, and is also used to dilute paints and is extremely flammable. It is also possible to add kerosene and mix it by heating to become a tender oil for use in painting. New colors and ordinary pastel pigments are commonly used for color matching, but high-grade pastels are not suitable. Resin can be an organic solvent extracted from petroleum, is cheaper than frankincense and is also used as a perfume. However in-line Coriolis flow meter is a perfect choice for the asphalt /bitumen flow measurement. Conventional liquid flow meters are difficult to meet their bitumen flow measurement requirements. Although the bitumen temperature is very high, the viscosity is still large, and the medium contains a small amount of solid particulate impurities. The operation temperature of the pipeline liquid asphalt is usually around 200 ° C(392℉). SenTec are always focusing on solutions for the high viscosity measurement according to the different high viscosity fluids features.Īsphalt flow measurement is always a technical problem because of the high viscosity and poor fluidity. Measuring fluids flow rate with viscosities over 100 mpa.s demand consideration by those charged with designing, operating and maintaining the equipment. are thick making them hard to pour and demanding additional power to pump, Low viscosity medium like pure water or milk are very thin and easily pumped. High viscosity fluids such as asphalt/ bitumen, Fructose,molasses, honey, glucose, resin etc.
