Analogue switches - Import export

The H250 M40 is the standard variable area (VA) flowmeter for the process and OEM industry. The VA meter combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. Additional electronic modules can be added or replaced at any time without process interruption. The H250 M40 is available in various materials and in many different versions. The sturdy all-metal flowmeter can be also used in applications with high pressures (up to 1000 barg / 14500 psig), temperatures (-196...+400°C / -320...+752°F) or aggressive media. It even allows installation in horizontal or fall pipes up to DN150 / 6". A special version for use in hygienic applications is also available. The H250 M40 is intrinsically safe and explosion-proof. Certain variants of the flowmeter with limit switch or analogue output are suitable for use in Safety Instrumented Systems (SIS).

This involves a play-free electronic switching cam encoder (abbreviated to: NOCA) with a maximum of four galvanically separated switching outputs (cams), which can be set by the customer and which are activated or deactivated depending on the relevant position of the drive shaft. A parameterisable multiturn absolute encoder with analogue interface plus the switching cam encoder printed circuit board with separate controller are integrated into the compact housing. The analogue signal and switching outputs can be parameterised separately using multifunction pins (MFP and PRE) in the connector.
