Meet SWT Portable Thermal Energy Meter.

SWT PTEM (Portable 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 connect directly to a single portable robust hard carrying case with integrated controller with an intuitive touch display and app-like interface. It also connects to your SCADA, PLC, or HMI systems through BACnet IP, Modbus RTU/RS485, 4-20mA and pulse outputs.

Advantages & Features

• PT1000 matched pair for highest performance on differential measurement

• Connects with your BACnet IP, MODbus RTU/RS485, Pulse, Alarm, 4-20mA, SCADA, PLC, or HMI

• Portable carrying case with integrated touchscreen & 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 PTEM 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 PTEM displays energy, flow, and temperature measurements in English or metric units.
