Product catalog summary
Overview: The document provides detailed specifications and operational guidelines for metallic disc target flowmeters, specifically the DP-65 and DP-500 series, designed for measuring the flow of liquids and gases. These flowmeters are suitable for various industrial applications, including water treatment, pharmaceuticals, and chemical industries.
Specifications:
  • Construction: Metallic, suitable for horizontal or vertical installation.
  • Size Range: DN 40 to DN 500.
  • Flow Rate: Water: 0.8 m3/h to 1600 m3/h; Air: 45 Nm3/h to 24000 Nm3/h.
  • Pressure Drop: Low, with a straight pipe requirement of 3 x DN before and after the meter.
  • Mounting: Between DIN 2501 flanges for DN 40 to DN 300 (DP-65) and with standard DIN 2501 flanges for DN 250 to DN 500 (DP-500).
Operation: The flowmeter operates by displacing a target disc with fluid flow, balanced by a coil spring. The disc's position, proportional to the flow rate, is transferred to the flow indicator via magnetic coupling, preventing fluid leakage.
Applications: Suitable for fluids with suspended solids, used in industries such as water treatment, pharmaceuticals, chemical, paper, heating and cooling circuits, swimming pools, fire protection, automotive, and power plants.
Technical Data:
  • Accuracy: DP-65: +/- 2.5% (standard), +/- 1.6% (special); DP-500: +/- 4%.
  • Temperature Range: Standard: -20°C to +130°C (Polyamide Coated Steel), -20°C to +180°C (Steel and SS 316L).
  • Pressure Ratings: PN40 for DN 40-80, PN16 for DN 100-200, PN10 for DN 250-500.
Models and Materials: Various models with different materials for body and internal components, including Polyamide Coated Steel and SS 316.
Options: Includes limit switches, electric and pneumatic transmitters, and totalizers. Transmitters provide 4-20 mA output, with ATEX certification for intrinsic safety.
Safety and Compliance: Conforms to EU directives for low voltage and electromagnetic compatibility, suitable for use in potentially explosive atmospheres.

• Metallic construction • Operates horizontally or vertically • Flow rate: • Straight pipe requirement of 3 x DN before & after • Local indication - 4-20 mA electric transmitter (2 or 4 wire) - Local or remote volume totalizer - Between DIN 2501 flanges (wafer) for DN 40 to - With standard DIN 2501 flanges for DN 250 to - Mounting with other flange standards on request The fluid flows through the meter and displaces the target disc with a force proportional to the flow. The disc movement is restricted with a coil spring until a force balance is achieved between the force from the fluid and the torsion of the spring. The equilibrium position of the target disc is proportional to the flow rate and provides The position of the disc is transferred to the flow indicator by means of magnetic coupling. This magnetic coupling avoids fluid leakage to the Disc Target
