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 complete with connector cable for assembly directly on the dosing head to monitor individual strokes using the float principle. The adjustment screw is used to match the partial flow flowing past the float to the set stroke volume so that an alarm is emitted if the level falls approx. 20 % below the required level. The permitted number of incompletely performed strokes can be selected between 1 to 127 on the gamma/ X and delta® metering pumps to ensure optimum adaptation to process requirements.
Suitable for metering pumps of the product ranges gamma/ X and gamma/ XL in material versions PP, NP, PV and TT.
Important: It is essential that you observe the minimum values for the stroke length. The design of the pressure stroke must be set to “fast”.
Suitable for the gamma/ X product range in material designs PP, PC, NP and TT. Complete with connector cable for assembly directly on the dosing head.
For monitoring the individual strokes based on the floating body 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 gamma/ L enables the permitted number of incompletely performed strokes to be selected between 1 to 127, ensuring optimum adaptation to process requirements.

Flow Control Dosing Monitor for Installation on Suction Side
Individual strokes are detected on the suction side, because the flow velocity is sufficiently high here. 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 delta® product range 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.
Your benefits
- Detects metering errors
- Issues alarm
- Can be used on discharge side or suction side
