The Smartmeasurement Differential Pressure Wedge Meters (ALDPWG) represents one of the many DP flow technologies available in our program. The ALDPWG meters consist of a flow body with (see below) wedge “V” shape throttle restriction. This restriction creates a differential pressure between ((P1) before and (P2) after the wedge (P2))-see below which is proportion to the square of the volumetric flow rate. The wedge restriction has no critical surface dimensions, or sharp edges, that will affect measurement accuracy as the result of normally expected wear. The ALDPWG meter is excellent for very low flows or low Reynolds number (Re. < 500), high-viscosity fluids which contains dust or solid particle or applications such as liquid cement, crude oil coal-tar oil, wastewater, hard pulp, asphaltic oil, coal-tar oil, wastewater, hard pulp, carbon black solution, two phase flows, etc. The ALDPWG meter must accompany a Differential Pressure (DP) transmitter to indicate, rate, total etc. The ALDPWG can be used with our ALDP3051 or ALDP1051 or customers own DP transmitters.
