Flow Measurement with EX Delta II Series
Product Description
The EX DELTA II Series
is a high-performance vortex flowmeter designed for measuring liquids, gases, and steam with outstanding accuracy. Its design combines a triangular-section bluff body with a piezoelectric sensor, ensuring stable and precise flow measurement.
The meter is user-friendly, cost-efficient, and low-maintenance due to its durable design with minimal seals. The replaceable sensor allows servicing and inspection without interrupting the flow.
With low pressure loss, the EX DELTA II saves energy and installation space. It features a large digital display, long-life battery operation up to 7 years, and optional explosionproof protection, making it suitable for a wide range of industrial applications.
Key Benefits
- High accuracy for liquids, gases, and steam
- Rugged design with replaceable sensor for easy maintenance
- Explosionproof versions available from -196 °C to +420 °C
- Large digital display with totalizers, instant flow, and alarm functions
- Flexible installation both horizontally and vertically
- Available as fixed type (DN 15–300 mm) or insertion type (DN 200–2000 mm, hot-tap from DN 400)
Technical Specification
The EX DELTA II vortex flowmeter operates in a temperature range of -30 °C to +460 °C, with special versions available for -196 °C. Explosionproof protection is available for -196 °C to +420 °C.
It is available in nominal diameters from DN 15 to DN 300 mm for the fixed type, and from DN 200 to DN 2000 mm for the insertion and hot-tap type. The hot-tap design allows maintenance and inspection without stopping the flow.
The integral converter features a digital display showing flow rate, total and resettable counters, and alarms. Power supply options include external power or battery with up to 7 years of continuous operation.
The meter can be installed horizontally or vertically, offering flexibility for replacing traditional area flowmeters. With the insertion type, construction and maintenance costs are reduced as no bypass piping is required.
The converter can be installed up to 200 m away from the flowmeter body (maximum 50 m for battery type).
