Claims (4)

1. Датчик активного давления для расходомера, предназначенного для измерения расхода текучих сред в закрытых трубопроводах, выполненный в виде корпуса (1) с фланцем (2) для присоединения через фланец (4) к трубопроводу (5), содержащий создающий активное давление элемент (8) со штуцерами (6, 7) для отбора давления, отличающийся тем, что создающий активное давление элемент (8) представляет собой, по меньшей мере, одну деталь с пазом, закрепленную на корпусе (1) или вырезанную в стенке корпуса, которая образует проходящую в продольном направлении щелевидную, раскрытую внутрь корпуса канавку (9), глубина которой (b) сначала возрастает, а затем убывает, при этом канавка ограничена параллельными боковыми стенками (10) и профилированным дном (13), а один из штуцеров (7) датчика давления сообщается с канавкой в точке ее максимальной глубины.1. The active pressure sensor for a flowmeter designed to measure the flow of fluids in closed pipelines, made in the form of a housing (1) with a flange (2) for connection through the flange (4) to the pipeline (5), containing an active pressure generating element (8 ) with fittings (6, 7) for pressure selection, characterized in that the active pressure generating element (8) is at least one part with a groove mounted on the housing (1) or cut in the wall of the housing, which forms a passing slit longitudinally a groove (9) that is opened inside the housing, the depth of which (b) first increases and then decreases, while the groove is bounded by parallel side walls (10) and a profiled bottom (13), and one of the fittings (7) of the pressure sensor communicates with groove at the point of its maximum depth. 2. Датчик активного давления по п. 1, отличающийся тем, что названная деталь с канавкой выполнена приваренной к корпусу или вваренной в стенку корпуса. 2. The active pressure sensor according to claim 1, characterized in that the said part with a groove is made welded to the body or welded into the wall of the body. 3. Датчик активного давления по п. 1 или 2, отличающийся тем, что вниз по течению потока в канавке (9), в ее радиальной плоскости (11), размещен второй штуцер (6) для отбора давления. 3. The active pressure sensor according to claim 1 or 2, characterized in that downstream of the flow in the groove (9), in its radial plane (11), there is a second fitting (6) for pressure selection. 4. Датчик активного давления по одному или нескольким из предыдущих пунктов, отличающийся наличием двух противолежащих элементов (8), создающих активное давление. 4. The active pressure sensor according to one or more of the preceding paragraphs, characterized by the presence of two opposite elements (8) that create active pressure.
