  • Harwil Q-16 Flow Switch

    Harwil® type Q-16 switches are used to signal, start, or stop electronically operated equipment when flow or no-flow conditions occur. Harwil’s patented elastomeric sealing system is superior to the metal bellows that are subject to metal fatigue and corrosion. This seal system has been field-proven for over a decade.

  • Kobold BGN Flow Meter

    Kobold® type BGN full metal variable flow meters and counters are for liquids and gases and consist of a meter tube with connections, a meter ring, and a conical float. They show the current flow rate in volume or mass per unit in time. Their design makes them ideal for processes under difficult and rough operating conditions.

  • Kobold DAA Flow Indicator

    Kobold® type DAA indicators feature a self-cleaning mechanism to guarantee rotor visibility. With a simple twist of the sight glass, integral wipers eliminate build-up which is then washed away by the media’s flow. The DAA will save both fuss and downtime.

  • Kobold DAF Flow Indicator

    Kobold® type DAF paddle-wheel flow indicators are recommended whenever visual flow indication is required. They can be installed in any position, as long as the flow remains in the direction of the arrow on the housing. Connections are available in 18” NPT through 1½” NPT, with a wide choice of materials for media compatibility. The DAF flow indicator may be rotated along its long axis, even during operation due to the rotatable fittings, allowing the windows to be aligned for optimum visibility.

  • Kobold DF Flow Meter

    Kobold® type DF paddle wheel flow meters are for low viscosity liquids. Their main feature is the incorporation of a multipole magnet ring embedded into the paddlewheel. As the paddle wheel rotates, the magnets, hermetically separated from the liquid media, induce a DC signal into a Hall-Effect sensor mounting on the device housing. Since the DC signal is proportional to paddlewheel rotation, an accurate flow rate reading is possible.

  • Kobold DFT Flow Meter

    Kobold® type DFT compact paddle flow meters embody the same rugged reliability of the workhorse DF series in a compact, more economical design. They are available in two material combinations. The nickel plated brass handles water, light chemicals and low viscosity liquids, while the PTFE version will stand up to aggressive chemicals. An open collector frequency output is standard with optional analog & controller outputs that offer LCD displays, analog flow transmitters, programmable relays and totalizer & batch control options.
