Flow meter

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.
Features
Product features
- Installation and connection dimensions according to DIN ISO 4064
- For horizontal and vertical installation
- The series is equipped with special 2-point sapphire bearing and stainless-steel axle as a single-jet impeller counter in dry-running design with magnetic coupling and has been conceived according to the latest technology
- To avoid disturbances caused by unclean water, only the impeller sits in the fluid path
- The counter can be rotated for easier reading
