Introduction 1
HRT1 HP-313
1. INTRODUCTION
The HRT1 is a loop-powered microprocessor-based flow rate indicator
and totalizer with HART Field Communications Protocol. The
instrument can accept a low-level signal from a magnetic type pickup
coil, logic level pulse signal, or contact closure on the signal input.
Pulses from the signal input are counted and converted into volume and
rate values based on flowmeter calibration settings in the instrument.
The total volume and flow rate is displayed on a two-line liquid crystal
display (LCD). The top line is an 8-digit Total Volume display and the
bottom is a 5-digit Rate display. A 4-20 mA analog signal proportional
to the flowrate is output on the current loop. The HRT1 is configurable
by way of the instrument keypad or via HART communications.
Figure 1 – HRT1 Front Panel Overview
Optional features include 20-point linearization to correct for
flowmeter non-linearities, a Scaled Pulse Output and 2 Alarm Outputs
configurable for Rate or Total.
The instrument may be housed in a NEMA 4X polycarbonate
enclosure, which may be wall mounted or directly mounted on a
flowmeter using an optional riser. Other options include panel mount
or an EX proof enclosure for hazardous areas.
