The ME995-2C and ME995-2CH VARIABLE DOSERATE CUBIC METRES preset batch controllers comply with quality assurance requirements for the concrete additives industry. They incorporate a preact (overflow deduct) feature, allowing speed batching of admixtures with near no overrun.

The display counting is indicated in total Cubic Metres load selected, and dispensed at the selected doserate per cubic metre. With it’s rotary selector knobs and push toggle switches, command operations are user friendly. The batch operator has important visual indication of the batch quantity selected, as shown on the numbered selector dials.

With the ME995-2C being of the same dimensions and using the 10-pin Weidmuller receptacle plug as previous models, replacement or upgrade is instant, with no re-wiring required. Interfacing the ME995-2C with PLCs is an easy procedure, to incorporate the safety features of the Manu controller which is also effectively a backup preset batch facility.

The ME995-2C calculates selected dosage rates for the batch operator. The two top selector knobs are for dosage selection of liquid admixture to be dispensed, marked DOSAGE MLS x 10/ CUBIC METRE. A maximum doserate of 99 x 10 mls per Cubic Metre is selectable. The two or three bottom selectors are used for selection of CUBIC METRE concrete quantity. Maximum load is 9.0 CUBIC METRES (minimum is 0.1). The LED display digits count upward to the selected load in cubic metres, while dispensing the selected dosage rate ratio.

The ME995-2CH model calculates and dispenses in the same way, except that a higher doserate is selectable via the extra doserate selector knob fitted. A maximum of 900 x 10 mls /Cubic Metre can be selected.
NOTE: Usually an internal maximum dose-rate safety limit is fixed at time of order e.g. 200×10/m3 max. selection. Any doserate set above this will trigger the LIMIT alarm and stop operation.

A batch example would be:

  • Selected dosage rate 22 x 10 mls/cubic metre
  • Selected Cubic metre cement load of 5.5 cubic metres
  • Actual admixture volume received 220 mls x 5.5 = 1210 millilitres.
  • Display counts upward in 0.1 Cubic metre increments to set point of final 5.5


  • Variable doserate selection in cubic metres
  • Display indication in selected predosed cubic metres of concrete
  • LED display with status indicators
  • Preact function
  • Preset maximum limit
  • Missing pulse detection
  • Optional PLC/computer interface
  • Interchangeable with earlier ME188 models
