COMPRESSED GASES FLOW METERS

Thermal Gas Flow Meters

Thermal mass flowmeters are used in almost all industries

  • Automotive
  • Breweries
  • Chemicals & Petrochemicals
  • Dairies
  • Food production
  • Fueling with gas
  • Mining
  • Petroleum (oil & gas)
  • Pharmaceuticals
  • Power Plants
  • Pulp & Paper industries
  • Shipbuilding
  • Steel & Metals industries
  • Textile industries

For these applications we provide insertion and in-line flow meters, for small and big diameter pipes, for compressed air, process gases such as Carbon Dioxide, Argon, Nitrogen, Oxygen, and explosive gases like Natural gas, Hydrogen, and Bio Gas.

Natural Gas Flow from the Main into Plant
Thermal mass flow meters are ideal for natural gas flow measurement and monitoring from the main in to the plant to improve energy management.

With concern for energy consumption, monitoring the instantaneous natural gas mass flow rate coming into the plant is critical because it provides information about the plant’s natural gas demand. The conventional billing meter only reports consumption over a fixed period of time (i.e. monthly). Whereas, a thermal mass flow meter monitors flow rate, as well as consumption; thus, it provides real-time feedback about plant upset conditions, peak demand, inefficiencies and wasted energy.

The Plant Manager, Maintenance Manager, or Energy Engineer all benefit from the readily available information that comes from a gas line, of an independent mass flow meter, entering the plant. Furthermore, the newly promulgated ISO 50001 standards define the best practice for energy management, and a rate flow meter in series with the billing flow meter can play a big role.

Gas Flow Measurement
Sigma provides both easy-to-install insertion thermal mass flow meters as well as in-line thermal flow meters, with built in flow conditioners that measure and report the mass flow rate of natural gas.

This type of direct mass flow meter does not require separate temperature or pressure transmitters, has no moving parts, is highly accurate and repeatable, and has negligible pressure drop.

Most importantly, our Thermal Mass Meters have extraordinary rangeability, providing the dynamic operating range and sensitivity necessary to account for a wide range of plant gas demand, whether it be at peak loads, or during a third shift with minimal gas requirement.

The meters not only support the tradditional the traditional 4-20 mA outputs and pulse outputs, but also options for HART, Modbus and M-Bus interface. Other options include ATEX: II 2 G Ex d IIC T4 .for some models.
