DIAPHRAGM CRITICAL FLOW INIDCATOR DICT-50, DICT-100

FOR MEASURING GAS FLOW WHILE DRAINING CRITICAL DISCHARGE THROUGH DIAPHRAGM WITH GAS EMISSION INTO ATMOSPHERE

DESCRIPTION AND OPERATING PRINCIPLE

DICT-50 or DICT-100 is designed for measuring pressure in a well and may be integrated into a wellhead equipment.  
DICT consists of body with a slick tubing thread as per GOST 633-80 on one end. On the other end – metric thread with a recess/seat for a diaphragm/orifice plate which is seated and compressed by a nut and handles. The other end is connected with flare line or welded into the line along with a choke.  
A set of DICT has up to 29 diaphragms of various diameters (quantity may be changed upon Client’s request). An orifice of the diaphragm/orifice plate is selected based on specific well rate.  
In addition, DICT can be fitted with a measuring tube which can be nippled up directly to DICT. Alternitavely, the tube can be connected using 3.5 inch tubing subs at a required distance. Then, pressure and temperature gauges can be set on the tube, and flow measurements can be taken in the flow section of the tube.
