MODEL NUMBERS
PET-1 0 to 10 VDC analog output
PET-3 4 to 20 mA analog output 3-wire
PET-7 4 to 20 mA analog output 2-wire

The PET Series converter receives frequency input and
converts it to a proportional 4-20mA or 0-10V analog
output. It has been designed to fit a compact "ELBY"
explosion-proof enclosure. The frequency range is field
selectable to fit most applications. ZERO and SPAN
adjustments make it easy to calibrate to almost any
measurement range. This PET is designed for use with
the Lo-Co Series and TriFlo Series flowmeters.
