What sets the Helios apart from other Large Display Meters is its dual line display with super bright LEDs that can be read even in bright sunlight and up to 100 feet away. Based on Precision Digital’s popular line of ProVu® digital panel meters, the Helios can satisfy a wide variety of level, flow, temperature, pressure, & weight applications. It is available with models that accept 4-20 mA, thermocouple, RTD, pulse, strain gauge, AC and DC volts and current, and even Modbus®.
Go with the Helios PD2-6200 when you want to display both flow rate and total at the same time from a 4-20 mA output flowmeter. The PD2-6200 can display both flow rate and total in six full digits and can also be configured to display non-resettable grand total. The PD2-6200 can even display open channel flow using its programmable exponent function. The PD2-6200’s NEMA 4X, IP65 rated field mountable enclosure, super bright LEDs, and wide operating temperature range make it perfect for outdoor applications.
