Multimag ITRON Woltex DN250 20in
Brand: ITRON TMIIWoltex is a horizontal helix Woltmann meter, available in sizes from DN 50 to 500.
Extended Approved RangeWoltex is approved with normal flow range as per ISO 4064-1:1993, as class B and also, with superior permanent flow-rate. It means that one size (DN) has 2 different flow range :- N for Normal Permanent Flow Rate;- G for Greater Permanent Flow Rate;Greater version is special for metering points where peak flows are recurrent.
