Two versions are available. One intended for single shot dosing with a built in delay to avoid accidental dose repeat and one with no delay and higher accuracy calibration for filling applications.
Both of these versions are then available with Low level sensing (-LL) which come complete with a float switch assembly with a maximum insertion depth of 250mm.
