Project Matching

Flow and Two Temperatures Become an Energy Reading

Keep the flow sensor, temperature pair and calculator matched as one metering package.

Measure the Flow

The ultrasonic flow sensor measures the water passing through the heat-exchange circuit.

Read Both Temperatures

The matched temperature pair measures the supply / return difference.

Calculate & Manage

The calculator determines thermal energy. Add remote reading or prepaid valve control with the selected route.

Specify heating or cooling duty and follow the selected model instructions for supply/return installation and temperature-sensor placement.

Before You Order

Frequently Asked
Questions

Product, installation and system questions for your project.

Discuss Your Requirements

How is a heat meter different from a water meter?

A heat meter combines flow measurement and a matched supply/return temperature pair to calculate thermal energy. Water volume alone does not measure heating or cooling consumption.

Which management option should I choose?

Choose standard metering for consumption measurement, NB-IoT for centralized remote readings, or the dedicated IC-card prepaid design for payment before use and valve control.

What flow and installation data do you need?

Send the required DN, normal and peak flow, available installation length, connection type, and supply and return temperatures. Standard and NB-IoT models use Qp for permanent flow and Qs for maximum flow.

Will the NB-IoT meter work with our platform?

Confirm local network coverage, supported operator bands, platform protocol and reporting requirements before ordering. The communication configuration must match the receiving system.

Does the standard heat meter include prepaid control?

No. Select the dedicated IC-card prepaid assembly with its motor-controlled valve and compatible card and vending system.
