5.3.1.2 Fluids handled
▪ Hot water for heating systems, with or without glycol (≤ 60 %)
▪ Cold water for air-conditioning systems, with or without glycol (≤ 60 %)
▪ The fluid handled should meet the requirements as specified in VdTÜV/AGFW
TCh 1466 or VDI 2035.
▪ Only limited measurements of fluids containing gas or air can be made with
ultrasound equipment. Proper venting of the systems is therefore essential.
▪ Drinking water (BOA-Control EKB / BOA-Control IMS EKB models only)
▪
Service water
▪ Not suitable for steam or fluids liable to attack EPDM and the electrostatic plastic
coating.
▪
Other fluids on request.
