Composer Elite Operating Manual
1.1 Introduction
Composer Elite™ is designed to measure the precursor concentration of binary
gases. It is optimized for operation at pressures as low as 26.66 kPa
[200 Torr] and temperatures as high as 65°C. The Composer Elite System
provides unsurpassed precision and reproducibility when measuring small
concentrations of heavy molecular weight components in a lower molecular weight
carrier gas.
1.1.1 Description of the Composer Elite System
The Composer Elite System consists of:
A Sensor Control Unit which sends/receives electrical signals to/from the
Acoustic Sensor. The Sensor Control Unit provides an LCD display and
interface for user interaction (see Figure 1-1).
An Acoustic Sensor which interfaces to the process gas tubing and forms the
physical basis for the speed of sound measurement (see Figure 1-1). Two
versions of Acoustic Sensor are available:
Chapter 1
Introduction
Standard Acoustic Sensor, for use with hydrogen or helium carrier gas at
flow rates up to 2000 sccm, or for carrier gases of any molecular weight at
flow rates up to 1000 sccm.
High Flow Acoustic Sensor, for use with nitrogen carrier gas or a higher
molecular weight carrier gas, at flow rates between 1000 and 2000 sccm.
An Interconnect Cable which connects the Sensor Control Unit and
Acoustic Sensor.
An optional 24 V(dc) Power Supply which provides power to the
Sensor Control Unit.

CAUTION
2.1 Composer Elite Installation Guidelines
The requirements and recommendations in section 2.1.1, section 2.1.2, and
section 2.1.3 must be reviewed and understood before Composer Elite is installed
as described by section 2.2, Composer Elite Installation, on page 2-8.
2.1.1 Pressure, Temperature, and Tubing
2.1.1.1 Maximum Pressure
Reliable measurement of concentration to absolute pressures as low as 26.66 kPa
(200 Torr) requires relatively thin and flexible diaphragms to be used so that
sufficient acoustic energy may be transmitted.
There is a possibility that the diaphragms may destructively rupture if an absolute
pressure greater than 826 kPa (6200 Torr) is applied. A secondary containment
chamber is built into the Acoustic Sensor to prevent process gases from escaping
the Acoustic Sensor in the event of a diaphragm rupture.
Chapter 2
Installation
Do not connect the Acoustic Sensor to process tubing
that can exceed an absolute pressure of
826 kPa (6200 Torr). Exposing the Acoustic Sensor to
excess pressure may cause catastrophic diaphragm
failure or may stretch the diaphragms, requiring on-site
reference zeroing (see section 4.1.2 on page 4-1).
A certified rupture disk should be installed upstream of
PN 074-566-P1B
the Acoustic Sensor to limit any possible over-pressure
to less than 826 kPa (6200 Torr).

2.1.1.2 Pressure and Tubing Size
The Composer Elite System is designed to operate with the gases in the Reactor's
process tubing at a pressure of 26.66 to 133.3 kPa (200 to 1000 Torr). The inner
diameter of the inlet and outlet tubes on the Standard and High Flow Acoustic
Sensors were designed to optimize performance at low pressures; however, the
Reactor’s process tubing may be of any appropriate size without degrading
Composer Elite performance.
2.1.1.3 Heated Process Tubing and Acoustic Sensor Temperatures
Operation of the Acoustic Sensor at a temperature slightly higher than the process
gas tubing will help prevent material from condensing inside the acoustic sensor.
INFICON recommends the following temperature settings:
The Temperature Setpoint 1 setting for the Acoustic Sensor's resonant
chamber temperature should be 5°C or more above ambient temperature.
See section 3.3.2.7, Sensor Parameters Screen, on page 3-12.
The Temperature Setpoint 2 setting for the Acoustic Sensor's inlet tube
temperature should be above the Temperature Setpoint 1 setting. Typically
start out with this temperature three degrees above Temperature Setpoint 1.
The inlet tube heater is designed to minimize zero point offset caused by large
flow rate changes. The optimal setting will depend on process conditions.
See section 3.3.2.7, Sensor Parameters Screen, on page 3-12.
