Nova flow

Product catalog summary

Introduction: The Nova-Flow Series by Hoffer Flow Controls is a versatile range of flow computers designed for various applications including rate and total flow display, batch control, and thermal energy measurement. With over 500,000 configurations, these devices support up to four flowmeter inputs and multiple temperature, pressure, and density inputs. They offer a variety of outputs and control interfaces, including up to three serial communication ports.

Features: The series includes Nova-Flow, Nova-Batch, and Nova-Energy models, each supporting different numbers of inputs and outputs. Key features include two-stage batch control, multiple batch modes, flash memory, infrared optical port, and Windows-based setup software. All models offer two-level password protection, multi-function self-diagnostics, and stainless steel front panel microswitches.

General Specifications: The display features a 128x64 graphical interface with LED backlight and adjustable contrast. The keypad includes 3 softkeys and 14 assigned keys. The CPU is a 16-bit, 40 MHz processor with 512 kB flash memory. Environmental specifications include an operating temperature range of -20°C to 50°C and storage temperature range of -40°C to 85°C. The enclosure is a 1/2 DIN panel mount with optional explosion-proof NEMA 4X.

Power Supply and Compliance: The power supply options include 10 to 30 Volt DC and 110/220 AC. The devices meet various standards such as CE, AGA, OIML, ISO, and NIST Handbook 44.

Modules and Expandability: The base unit supports one flowmeter input and 8 digital I/O lines, with 8 expansion slots for optional modules. Modules include dual RTD and analog input, analog output, dual relay, RS232 and RS485 ports, second channel flowmeter, and high-speed pulse out.

Installation and Security: Installation drawings are provided for different configurations. Security features include audit trails with time/date/ID stamping and double storage of process variables.

Quality Assurance: The quality system is certified to ISO 9001 standards. Specifications are subject to change, and users should verify current specifications with the manufacturer.
