Chapter 1 Introduction

Sierra’s Side-Trakand Auto-Trakmass flow meters and con- trollers are designed to accurately measure and control flows of process gases. This instruction manual covers the installation, op- eration and maintenance of the entire Side-Trak and Auto-Trak product lines, which include the following Sierra models:

830 Side-Trak Mass Flow Meter

840 Side-Trak Mass Flow Controller

860M Auto-Trak Mass Flow Meter with RS-485 interface

860C Auto-Trak Mass Flow Controller with RS-485 interface

Sierra’s mass flow meters and controllers offer a broad range of sizes, control electronics, process connections, cables and connectors for flexibility and versatility. The meter’s patented straight sensor tube with access ports permits easy cleaning and reduces maintenance down-time. The platinum sensor eliminates zero-drift and ensures long-term repeatability. The primary standard calibration ensures starting point accuracy and NIST traceability. All wetted surfaces are constructed of 316 stainless steel with Viton® seals standard. Control- lers incorporate either an electromagnetic valve (up to 500 slpm) or a motor-operated rotary valve (100 slpm to 200 scfm). The Auto-Trak

860digital microprocessor features automatic bridge-balancing cir- cuitry and provides simultaneous analog and digital RS-485 commu- nication.
