Flow measuring orifice

Description		Danfoss flow measuring orifices are used to
		precisely determine the flow in water based
		heating, cooling or potable water systems.
		This determination is done by measuring the
		differential pressure across the fixed orifice,
		which has a well known Kv value.
		Differential pressure is measured with PFM 5000
		or other measuring device that can convert
		differential pressure to flow.
		Main data
		• Suitable for heating and cooling applications
		• Supplied with 2 pcs. of test plugs for needles
		• working temperature: –10 … 130 °C
		• PN 25
		Materials
		• Fixed orifice: Stainless steel
		• Measuring points: Dezinfication free brass

Instalation	The measuring orifice should be installed
	between two counter flanges.
	Check that these counter flanges are parallel and
	that the gaskets are according to given standard
	for flanges. Check also that the measuring
	orifice and the gaskets are correctly centered
	before tightening.
