A fixed-installation solution for energy and flow measurement

Meet SWT Thermal Energy Meter.

SWT TEM (Thermal Energy Meter) is a completely non-invasive compact thermal energy meter designed for thermal energy measurement. The system measures flow, temperature, and energy (BTU) all in one system with external power and industrial communications designed for long-term monitoring.

Ultrasound flow sensors and PT1000 temperature sensors install on the outside of your pipe to sense flow as well as supply and return temperature—all through the pipe wall. The system is highly accurate, with a matched pair of PT1000 RTD temperature sensors for the highest performance.

Both the flow and thermal sensors come prewired to a single wall-mounted controller with intuitive touch display and app like interface. It also connects to your SCADA, PLC, or HMI systems through BACnet IP, MODbus RTU/RS485, or pulse outputs.

Advantages & Features

  • PT1000 matched pair for highest performance on differential measurement

  • Connects with your BACnet IP, MODbus RTU/RS485, Pulse, SCADA, PLC, or HMI

  • Wall mounted touch screen & app

  • Completely non-invasive solution

  • SWT Reciprocity Architecture for zero-point stability

  • Simple, quick & cost-effective installation

  • One-piece flowmeter construction; no assembly

Intuitive Touch-Screen Display

The built-in touchscreen is your access to the TEM App featuring a familiar user experience similar to our Cypress and Orcas mobile apps. Swipe, tap, scroll, and (if needed) use an on-screen keyboard to specify parameters. The display is backlit for maximum visibility in darkness or sunlight.

Preset menus, plain-language dialogs, and intuitive navigation let you easily choose from pre-loaded settings. There is little to no programming setup required: simply connect power, mount your flowmeter and RTDs, and in seconds the SWT TEM displays energy, flow, and temperature measurements in English or metric units.
