Rotary Meter Delta® - BEMUTATKOZÁS

1 Rotary Meter Delta . < Excellent metrological stability Delta meters are volumetric meters . The The movement is mechanically transmitted attested by customers over the flow of gas moves the pistons and each to the totaliser through the magnetic years rotation traps and transfers a specific coupling. < No influence of installation volume of gas. conditions nor stop-and-go flow rate on the metrology < Large rangeability approved by the DRIRE, NMI, PTB and various other official bodies Description Applications A Delta Meter is made of 5 main parts: Delta meters are designed to measure < Optimised pressure loss for low < A measuring chamber that is limited by natural gas and various filtered, and pressure network the body and the 2 base plates (1) non-corrosive gases.

External silicagel cartridge: accessory for volume converter to be adapted directly maintenance on the installed external onto the Meter , or at the most convenient silicagel cartridge for extreme conditions. place to the Meter to enable the converter Flange DN50 PN10/16-ANSI125, can be index to be easily read. delivered to adapt a 2040 Meter (thread Thermowells: these thermowells threaded connection) to flange connections DN50. 1/4 NPT, can be plugged onto the Meter . < Gasket filters from DN50 to DN150. This gives a flange-to-flange distance of They are retrofitable on the standard 171 mm. version (plugged onto the existing pressure Pete s plug : ideal device for filling tapping), or they can be installed on the lubricant in the cover of the Meter while versions equipped with extra-tapping.

7 Equipment is in service. It must be fitted The internal diameter of the thermowell is instead of the tap plug of the cover. 7 mm; it allows the mounting of the most Plugged on the pressure tapping, it can be standard temperature probes. used to measure the pressure and the temperature of the measured gas. Connection size: 1/4 NPT or 1/4 BSP. Maximum pressure of gas: 30 bar. Delta 2040 - Aluminium < Delta DN100 G250 with Corus PTZ. Features Flow rate m3/h to 65 m3/h G size G10, G16, G25 and G40.
