Power Supply Options

The RHE28 can be configured with one of three power supply options:

Universal AC Power – 100-240 VAC ±10% (48 to 62 Hz) (Part Number Code A1)
Wide Tolerance DC Power – 12-24 VDC ±10%, 4W (Part Number Code D1)
Dual Supply – 100-240 VAC ±10% (48 to 62 Hz) / 12-24 VDC ±10%, 4W (Part Number Code U1) This unique option provides inputs for simultaneous connection of both a universal AC and separate DC supply. The transmitter utilizes AC power when available but will switch to the DC supply in the event of an AC power outage. The DC supply can be a battery source. As an example, an RHE27 transmitter and connected sensor will operate for 10 days or more on a typical automobile battery.

RHECom Software

The RHE28 transmitter is a fully featured device with many sophisticated functions and configuration is necessary for proper performance of these functions. RHECom software is available in three versions – Free, Pro, and Pro+. RHEComFree is available for download at no extra cost or on a USB flash drive. RHEComFree allows the full setup of transmitter parameters and includes a useful data-logging function for monitoring the performance of the meter.

For a small one-time license fee, RHEComPro and RHEComPro+ offer additional insight and set up convenience menus. RHEComPro includes data logging, trending, and broad diagnostic capabilities. RHEComPro+ takes flow meter management one step further with a revolutionary fully functioning simulator application.

With the simulator, you can trial run your application from the convenience of your office, adjusting transmitter settings, setting alarms and filters, and creating transmitter configuration files for upload into the actual unit. The simulator is also ideal for training – it exactly mimics the front panel of the instrument display and buttons when clicked and includes controls for adjusting flow, density, and temperature readings just like the unit was in line!
