INTRODUCTION SYSTEM DESCRIPTION The flowrate indicator / totalizer model E112-P (also referred to as a unit) is an explosion proof microprocessor-driven instrument designed to linearize the flowmeter’s flow curve and to show the current flowrate, the totalized flow and the accumulated totalized flow, current and previous day total, and several historical day totals.
● One flowmeter with a passive or active pulse, NAMUR or coil signal output can be connected to the E112-P. Several options are available for powering the sensor. ● Status input to reset total remotely or to lock the ‘clear total’ key.

E112-P Daily records The daily log records the daily record in the Daily logbook. This is done at one or two predetermined time(s) in the day; for example, before or at the end of a so called contract hour. This function can be used to determine the total of the previous contract hour, or trend the total over a certain period of time.
E112-P DATALOGGING (WITH TYPE ZL) LOG INTERVAL Selects the interval at which an interval record is created. The interval log logbook can hold up to 1000 records. When it is full, it will overwrite the oldest record first. DAILY LOG Selects how many times a day a daily record is created.
Personnel must read and understand this Operating Manual before carrying out its instructions. ● The E112-P may only be operated by personnel who are authorized and trained by the operator of the facility. All instructions in this manual are to be observed.
