Metering Monitor for Low-Pressure Metering Pumps
Monitoring of the individual strokes in accordance with the float principle.
Product description
Flow Control Dosing Monitor for Discharge Side Installation
Metering monitor assembly with connector cable for assembly directly on the dosing head to monitor individual strokes based on the float principle. The adjustment screw is used to match the partial flow flowing past the float to the respective stroke volume so that an alarm is emitted if the level is transgressed by approx. 20%. The permitted number of incompletely performed strokes on gamma/ X and gamma/ XL metering pumps can be selected as a figure between 1 to 127, ensuring optimum adaptation to process requirements.
Suitable for metering pumps of the gamma/ X and gamma/ XL product ranges in PP, NP, PV and TT material designs.
Please note: It is essential that you observe the minimum values for the stroke length. The design of the pressure stroke must be set to 'fast'
Note: The metering monitor Flow Control is only suitable for viscosities of less than 100 mPas.

Flow Control Dosing Monitor for Installation on Suction Side
Individual strokes are detected on the suction side where the flow velocity is sufficiently high. With water as the medium, the minimum stroke length is 30% and the suction stroke is normal, HV1 or HV2.
Suitable for metering pumps of the gamma/ X and gamma/ XL product ranges with slow compression stroke.

Overview
Monitoring the metering process
The dosing monitor identifies the most frequent causes of metering errors, such as overpressure, cavitation, air bubbles or faulty valves.
Dosing monitors are available for discharge side and suction side installation.
The benefits for you
- Detects metering errors
- Issues alarm
- Can be used on discharge side or suction side
