HIT-4U
HP-327
1. INTRODUCTION
The HIT-4U is a battery, DC or loop-powered microprocessor-based
flow rate indicator and totalizer with data logger and Modbus
Communications Protocol. The instrument can accept a low-level
signal from a magnetic type pickup coil, a DC pulse signal, contact
closure or modulated carrier pickup (MCP/RF). Pulses from the signal
input are converted into volume and rate values based on flowmeter
calibration settings stored in the instrument. The total volume and flow
rate are displayed on a two-line liquid crystal display (LCD). A 4-20
mA analog signal proportional to the flowrate is output on the current
loop. The HIT-4U is configurable from the instrument front panel
keypad or via Modbus communications.

Optional features include 20-point linearization to correct flow meter
non-linearity, a Scaled Pulse Output and Alarm Output configurable for
Rate or Total.
Enclosure options include NEMA 4X, panel mount, IP66 rated
aluminum and Ex d certified for hazardous areas. Most enclosure
options may be wall mounted or directly mounted on a flowmeter using
an optional riser.
