Description

The Steca TA VM1 / TA VM2 flow meters allow flow rate measurement of the water/water-glycol heat transfer fluid.

A contact maker (e.g. reed relay) is used to send a pulse to the solar thermal controller every time a defined quantity of fluid has passed through the system (e.g. 1 litre = 1 impulse or 10 litres = 1 impulse). At the same time, the controller determines the temperature difference between the supply and return temperatures and then calculates the heat quantity generated, by using this difference, the flow rate and the specific material characteristics of the heat transfer fluid. The heat quantity calculated is then finally displayed by the controller in kWh.
