Overview

Details for GFM-1108

Dwyer Instruments GFM-1108 Gas Flow Meter The Dwyer Instruments GFM-1108 is a precise gas flow meter designed for measuring flow rates from 0 to 2 liters per minute (LPM). Its compact size and lightweight design make it ideal for portable or benchtop use. Featuring a durable construction and robust sensors, the GFM-1108 delivers accurate and reliable measurements, even in demanding environments. It utilizes a simple two-button interface for easy operation and calibration. The large, easy-to-read LCD display provides real-time flow measurements, allowing for precise control and monitoring. Additionally, the GFM-1108 offers programmable alarm settings, ensuring compliance with safety or process requirements. Key Features: * Flow range: 0-2 LPM * Accuracy: Â±0.5% of full scale * Repeatability: Â±0.2% of full scale * Compact and portable design * Rugged construction for harsh environments * Simple two-button interface * Programmable alarm settings * Large, backlit LCD display Applications: * Gas leak detection and monitoring * Flow rate measurement in medical devices * Industrial process control * Environmental monitoring * Laboratory analysis

Series GFM Gas Mass Flow Meter

Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable

Series GFM Gas Mass Flow Meters combine a straight tube sensor with a restrictor flow element to provide high accuracy and repeatability. Flow rates are virtually unaffected by temperature and pressure variations. Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout. Units can be used with Series GFT Flow Totalizer for applications requiring totalization. Series GFM includes a NIST traceable certificate.

Note: These units require a cable, see GFM-CBL4 or GFM-CBL5, depending on your needs.
