Authentic Endress+Hauser Prowirl D 200 (7D2C / 7D2B) Wafer Vortex Flowmeter with factory calibration. Rapid global dispatch and 2-hour technical quotation response.
The Endress+Hauser Prowirl D 200 (7D2C) is built for process leads and skid equipment builders who need high-accuracy steam, gas, and liquid measurement in cramped pipe racks without expensive piping redesigns or fluid stagnation.

Prowirl D 200 provides saturated steam mass and heat energy flow calculations using its optional integrated temperature sensor. It eliminates the need for separate temperature transmitters and flow computers in plant boiler rooms and sub-metering header lines.
The meter continuously tracks volume and standard volume flow for nitrogen, compressed air, and process gases. Selecting meter sizing based on operating density, pressure, and velocity prevents signal loss at lower flow boundaries.
With its standardized 65 mm (2.56 in) face-to-face length, the wafer body fits directly into legacy differential pressure orifice plate gaps. Plants replace high-maintenance DP impulse lines without cutting, welding, or extending existing pipeline footprints.
The flangeless design relies on factory-supplied centering rings for rapid alignment between mating flanges. This lightens overall skid weight and minimizes installation space requirements in crowded utility modules.

The active 7D2C series maintains the identical 65 mm face-to-face dimension and centering ring system as the obsolete 7D2B model. It mounts directly between existing plant flanges without piping alterations.
The 7D2C update incorporates internal Heartbeat Technology. Maintenance teams run electronic verification checks and monitor sensor drift directly through HART or control room interfaces, fulfilling ISO 9001 compliance without line shutdowns.
When replacing a legacy 7D2B meter from an older engineering BOM, check signal outputs, hazardous area approvals (ATEX, IECEx, CSA), and local pressure ratings to ensure complete functional parity before placing an order.
Vortex meters require fully developed flow profiles. Maintain a minimum of 15 DN straight pipe upstream following a single elbow, and up to 40 DN downstream of pressure reduction valves to prevent turbulence errors.
Flange gaskets must be centered precisely using the factory alignment rings. Gaskets that protrude into the inner pipe diameter generate abnormal vortices, causing flow signal noise and erroneous readings.
Q: Is the legacy Prowirl D 200 7D2B model code still available?
A: No. The 7D2B generation is officially discontinued by Endress+Hauser. The current active successor is the Prowirl D 200 7D2C, which offers full mechanical compatibility and upgraded diagnostic software.
Q: Does Prowirl D 200 measure saturated steam mass without external sensors?
A: Yes. When configured with the optional built-in temperature sensor, Prowirl D 200 automatically calculates saturated steam mass flow and heat energy values internal to the transmitter electronics.
Q: What operating data is required for a Prowirl D 200 price quote?
A: Provide line size (DN), fluid type, operating temperature, operating pressure, minimum and maximum flow rates, and required area approvals (e.g., ATEX or non-hazardous) for an accurate technical RFQ.
