Daniel DRT-899 Pulse Input Rate/Totalizer
The compact, explosion-proof Daniel™ DRT-899 Pulse Input Rate/Totalizer provides real-time flow data in an easy-to-read, backlit display.
Ideal for any liquid metering application, the device offers the flexibility to easily view a 5-digit flow rate or total on the top line along with the ability to toggle between user-selectable, 7-digit values on the bottom line, including unit/tag, total or grand total. During programming, operators simply enter the meter's K-factor and the preferred unit of measure (i.e. pulses/gallon, etc.) and the DRT-899 automatically converts the data into the correct units. No additional conversion factors are necessary, simplifying programming and eliminating manual calculation errors.
