DigitalFlow™ GS868

Product catalog summary

Overview: The DigitalFlow™ GS868 is an ultrasonic steam mass flowmeter designed for measuring the mass flow rate of saturated or superheated steam. It offers no pressure drop, wide rangeability, ease of installation, low maintenance, and high accuracy.

Specifications: The flowmeter uses the correlation Transit-Time™ technique with compact ultrasonic transducers installed in the pipe. It measures the difference in upstream and downstream transit times to calculate velocity and volumetric flow rate. Mass flow is calculated using temperature and pressure inputs and built-in steam tables. It supports pipe sizes from 2 in to 48 in (50 mm to 1200 mm) and velocities from 0.1 to 150 ft/s (0.03 to 46 m/s).

Features: Key features include bidirectional flow measurement, no moving parts, no pressure drop, wide rangeability with a 1500:1 turndown ratio, non-obstructive flow measurement, tolerance to dirty streams, low maintenance, and suitability for high temperatures. A two-path measurement option is available for maximum accuracy.

Applications: The flowmeter is suitable for various industries, including HVAC, pneumatic power systems, food and beverage, water purification, chemical and petrochemical, electric power generation, steel industry, public works, and manufacturing.

Installation and Operation: The system consists of transducers, preamplifiers, and an electronics console, which can be installed as part of a flowcell or directly into the pipeline. The console can be located up to 500 ft (150 m) from the transducers. It offers local and remote programming and output options.

Outputs and Interfaces: The flowmeter provides digital and analog output options, including RS232, RS485, Modbus, Ethernet, and Foundation fieldbus. It features a menu-driven operator interface and data logging capabilities for over 43,000 flow data points.

Technical Specifications: The flowmeter operates within a temperature range of –4°F to 131°F (–20°C to 55°C) and a pressure range of 0 to 2700 psig (1 to 187 bar), with optional higher pressure capabilities. It complies with European EMC and PED directives.

Additional Options: The PanaView PC-interface software allows communication with a PC for site management and data logging. The flowmeter demonstrates minimal permanent pressure loss compared to other flowmeter types.

With its broad range of measurement velocities and its ability to measure flow in any pipe from small to very large, one DigitalFlow GS868 meter does the job of several conventional meters. It handles pipes from 2 in to 48 in (50 mm to 1200 mm) in diameter and velocities from 0.1 to 150 ft/s (0.03 to 46 m/s)—in either direction—in saturated or superheated steam. For maximum accuracy, use a two-channel meter to measure along two different paths at the same location. A two-channel meter can also measure the flow in two separate pipes for additional cost savings. Straightforward installation is...
