autarkon - Model EDZ 150.1 (157.1) -Differential Pressure Meter

Function

• measuring and registering the standard volume, the volume or the mass of air, nitrogen, carbon dioxide, argon, etc. (with pressure and temperature compensation)
• measuring and registering the mass or energy of steam

Technical properties

• highly suitable for billing purposes
• traceable standardized measurement, based on international valid rules and regulations, large confidence range
• very short needed inlet and outlet pipes (typical 8x DN / 0x DN), with an additional uncertainty of 0,5 % calculated, the needed inlet pipe is 4 x DN
• small residual pressure loss (typical 100 to 150 mbar)
• wear resistant and dirt insensitive (venturi effect)
• insensitive to dampness and vibrations
• application areas compressed air and other technical gases
• compact, highly-integrated measuring system (pressure and temperature compensationintegrated in the measuring device). Therefore, easy and cost-effective installation
• wide dynamic range (20 : 1) and small measurement uncertainty (1 % of measured value)
• fast data acquisition and calculation (approximately 10 times per second)
• long term stability, because of automatically hydraulic zero balance and self test
• plausibility and accuracy test during operation
• low-maintenance
• signal output:
• standard 2x (0)4-20 mA / 2x frequency / pulse / status, M-Bus / Modbus (optionally up to 6x (0)4-20 mA, 6x frequency / pulse / status, additional M-Bus interface, RS 485, Ethernet interface)
• parametrisation at PC-Software and/or manual at key pad EMC saved plastic housing for wall mounting (optional with separate display)
• optionally with two counters - e.g. for combined heat-/cold measuring or   bidirectional measuring
• power supply 230 VAC (optionally 24 VDC)
