The OPTISWIRL 2100 is a Vortex flowmeter for basic utility applications in all industries. The 2-wire device is the ideal choice when it comes to reliable flow measurement of conductive and non-conductive liquids, (wet) gases or steam where high accuracy is not required. The flowmeter features the robust Vortex technology of the OPTISWIRL product series, but does without the high-end options of the more powerful OPTISWIRL 4200. This makes it one of the most cost-effective Vortex flowmeters in the market. This Vortex flowmeter is also equipped with the field-proven Advanced Vortex Frequency Detection (AVFD) technology for signal filtering, allowing stable measurements even under demanding process conditions.

There are different variants available for the OPTISWIRL 2100. The Vortex flowmeter comes as flange or space-saving sandwich (wafer) version. For a large measurement span even in pipelines with large diameters, a version with integrated nominal diameter reduction (F1R/F2R) can also be provided. Its remote field housing version (F) allows the signal converter to be installed up to 50 m / 164 ft away from the sensor. The Vortex flowmeter also holds approvals for use in hazardous areas.

The cone flowmeter is a differential pressure (DP) flowmeter specifically engineered for applications with high accuracy requirements and disturbed flow profiles in confined installation spaces. The cone meter body can be installed with 3D/2D straight upstream/downstream pipe length and is suitable for almost any application from natural gas to steam to liquid hydrocarbons. KROHNE offers the complete cone flow metering assembly with the flow element, DP transmitter, accessories, engineering, testing and documentation from one single source.

The cone is installed in the centre of the measuring tube forcing the fluid through an annular gap. A controlled turbulence region behind the cone flattens the incoming irregular velocity profile and induces a stable differential pressure that is sensed by a downstream centre tap. Designed according to ISO 5167-5 the effect of disturbed flow profiles is eliminated and high accuracies can be achieved even with short straight pipe length. The calculated flow coefficient has an uncalibrated uncertainty of < ±5% of measured value as defined in the ISO 5167-5. KROHNE typically supplies cone meters with uncertainties of < ±0.3% calibrated on fully accredited hot water calibration facilities.
