Inline flow sensors

Belimo’s inline flow sensors come in sizes up to 6” and offer automatic glycol measurement and compensation. The units have an inlet length of five times the nominal pipe diameter, no output length requirements and have a power consumption of 0.5 watts. Units are wet calibrated to ensure accuracy (+/- 2%) and repeatability (+/- 0.5%).…

Switching relay

Tekmar’s one-zone 301P switching relay operates a circulator in a hydronic system when the connected thermostat calls for heat. The control includes optional exercising to prevent circulator seizure when not in use, and an optional post-purge operation to reduce standby losses in the boiler. It features a 20 VA transformer, thermal…

Radiant heating mat
