The Helios large display process meter boasts specifications, features and functionality that make it the only large display process meter you will ever need. The big, bright 6-digit dual-line LED display that can be seen from 100 feet even in bright sunlight is the first thing you will notice about the Helios. After that, the number one feature that makes the Helios such a useful device is its built-in 24 VDC power supply to drive the transmitter as illustrated by the above diagram. This feature not only saves the cost of an external power supply, but also greatly simplifies wiring. In addition, there is a second 40 mA power supply provided with the 4-20 mA output option, evident also in the above diagram.

The above picture illustrates several other reasons why the Helios is the only large display process meter you will ever need. First off, is the Type 4X, NEMA 4X rated enclosure which means you can install the Helios indoors and outdoors, exposed to moisture, dust and other adverse conditions. The next thing to notice is the 6-digit dual-line display that can display numbers up to 999,999 on the upper line and show either a tag or the input in a different scale on the lower line.

Other key features include four relays and 4-20 mA output option, advanced signal input conditioning like automatic round horizontal tank linearization, function keys, pump alternation capability, and Modbus RTU serial communications. Finally, all these features and capabilities can easily be programmed with free MeterView Pro PC-based software.
