Stilling well is a cylinder shaped cage installed within a tank to protect level instrumentation such as displacer from fluid agitation that would result measurement error. The stilling well should be perforated (provided with holes) to allow the level of fluid inside and outside stilling well within a tank be always equal. Stilling well shall have diameter with size providing adequate gap between stilling well and displacer. This is to avoid liquid or particle being clogged in between. MOC : – SS304, SS316, aluminum Size, dimension and Certification as per requirement of customer.

We offer the Siphon Tube, which is connected between the pressure gauge and the process. The Siphon Tube is best suited for such applications where high temperature vapors or fluids are present or temperature.

This eliminates cost of installation of Differential Pressure Transmitter with impulse piping up to the orifice assembly. The transmitter is mounted on the orifice assembly through a 3/5 Valve H-type manifold. Available with line sizes of 2″ & below. However due to process temperature limits of the transmitter, this assembly cannot be used for process temperatures above 120 Degrees Centigrade. The assembly consists of a orifice plate between two integral blocks having corner tap. Generally meter run pipe is recommended with upstream length of 750mm and downstream length of 250mm. The pipes are welded to the blocks with end flange.  Advantages of using Integral Meter run assembly Use of an integral orifice flow meter will eliminate the three measurement inaccuracies recorded in small orifice line installations. The Integral Orifice honed body reduces ID uncertainty By inserting precision bored upstream and downstream sections of pipe, the velocity profile distortion due to pipe roughness is reduced.

The Differential Pressure Transmitter has an impulse piping that is connected to the orifice assembly. The differential pressure transmitter is attached to the orifice assembly, with the aid of a 3/5 Valve H-type manifold. Integral Flow Orifice Assembly comprises an orifice plate, which is attached between two integral blocks that have a corner tap. The meter-run pipe, which the Integral Flow Orifice Assembly uses, should have upstream length of 750mm & a downstream length of 250 mm. These pipes need to be welded to the integral blocks with end flange. Since the transmitter cannot take high temperature, the Integral Flow Orifice Assembly works in a process temperature that is above 120 degrees centigrade. Availability : line sizes of 2� & below Advantages Of Using Integral Meter Run Assembly : The use of an integral orifice flow meter eliminates the three measurement inaccuracies, which are recorded in the small-sized orifice line installationsThe honed body of the integral orifice flow meter considerably decreases ID uncertaintyDirect mounting of the DP transmitter is possibleThe velocity profile distortion of the pipe is reduced due to the insertion of precision bored downstream and upstream sections of pipeThe plate misalignment is reduced, owing to the self-centered design of Integral Orifice PlatesDecrease start-up time due to high flexibility of innumerable process connectionsHigh reduction (approx.. 50 %) in leak pointsComplete elimination of impulse linesMinimization of line plugging is done by removing long lines, crevices and small-bore ports, due to the direct mount designReliable installations
