For the ZENNER Woltman WPH-H the connection and mounting dimensions are made in accordance with DIN ISO 4064. On request, a high-temperature version (150 ° C) and a high-pressure version (PN 25) are also available.
WPH-H / WPHI-H design for horizontal and vertical mounting. This type of meter is distinguished by high load capacity, low pressure loss and short installation length. It is ideal for heating circuits with an almost constant volume flow (secondary heating circuit).
