Measurement Principle

Measuring Steam Consumption Through Condensate

The measurement approach is based on a straightforward mass relationship: one pound of steam produces one pound of condensate. Measuring the condensate therefore provides a practical method for determining steam consumption.

Cadillac condensate meters measure the volume of returning condensate and adjust for its density to provide a totalized reading in pounds. This allows condensate measurement to support steam accounting and system-performance evaluation.

Why Measure Condensate?

Turn Condensate Return Into Useful System Data

Whether steam is being measured as a commodity or the objective is to evaluate system operation, condensate measurement provides a practical way to quantify the liquid returning from a steam system.

Steam Accounting

Convert measured condensate into a totalized indication of steam consumption.

System Evaluation

Use measured return data when assessing the operation and efficiency of a steam system.

Totalized Measurement

Track accumulated condensate rather than relying only on an instantaneous flow indication.

Installation Flexibility

Select an appropriate measurement approach for gravity-return or pumped-condensate systems.

System Configuration

Gravity and Pumped Condensate Measurement

Meter selection depends on the condensate-return arrangement and the actual operating conditions. The CG is intended for gravity-flow or approved vacuum configurations, while the CMAG requires conductive liquid and a completely filled flow tube.

Gravity or Approved Vacuum Return

CG Gravity Condensate Measurement

The Cadillac CG Gravity Condensate Meter is a totalizing meter designed for full or partially filled gravity-flow piping systems. Vacuum-rated configurations may also be available for suitable vacuum-return arrangements.

Important: The CG is not designed for installation in a pressurised condensate line.

Consider this approach when:
  • Condensate returns freely under gravity
  • An approved vacuum-return configuration is being evaluated
  • The condensate line is not pressurised
  • Accumulated total measurement is required
Pumped or Flooded Gravity Return

CMAG Condensate Flow Measurement

The Cadillac CMAG is a totalizing magnetic flow meter for compatible pumped or gravity condensate applications. Its full-bore design provides an obstruction-free flow path without moving measuring components.

Critical requirements: The condensate must have conductivity of at least 3.0 µS/cm, and the CMAG flow tube must remain completely flooded during measurement.

Consider this approach when:
  • The condensate meets the minimum conductivity requirement
  • The piping keeps the flow tube completely full
  • Condensate is pumped or a gravity-system wet leg can be provided
  • An obstruction-free magnetic measurement method is preferred

Selection note: Confirm the return arrangement, line pressure, liquid conductivity, ability to maintain a full pipe, flow range, temperature, pipe size and installation conditions before selecting either meter. Very-low-conductivity condensate may be below the CMAG measurement threshold.

Selection Guidance

Information Needed to Select a Condensate Meter

Condensate-meter selection begins with the return-system configuration, liquid properties and actual operating conditions. These details determine whether a CG or CMAG measurement approach is appropriate.

Pay particular attention to line pressure, liquid conductivity and the difference between normal flow and the maximum flow that may occur during startup, peak demand or pump discharge.

Key limitations

The CG is not intended for pressurised condensate lines. The CMAG requires conductive liquid of at least 3.0 µS/cm and must remain completely flooded while measuring.

01 Return Arrangement

Confirm whether condensate returns under gravity, through a pump or within an approved vacuum arrangement.

02 Line Pressure

State whether the proposed meter location is atmospheric, under vacuum or pressurised. A CG must not be installed in a pressurised line.

03 Liquid Conductivity

Provide the expected conductivity. CMAG measurement requires a minimum liquid conductivity of 3.0 µS/cm.

04 Pipe and Full-Tube Conditions

Provide the pipe size, material and installation location. A CMAG flow tube must remain completely flooded during measurement.

05 Flow Range

Identify minimum, normal and maximum flow, including startup surges and intermittent pump-discharge conditions.

06 Temperature and Materials

State the expected condensate temperature and provide any information needed to confirm compatible construction materials.

07 Measurement Objective

Define whether the data will support billing, allocation, energy monitoring or system-performance evaluation.

08 Outputs and Integration

Identify the required totalizer, signal outputs, communications and control-system integration.
