![]() ![]() This is a personal thing but I hate those flow meters everyone goes on about especially that HTP thing which seems to have one of the highest set pressures around because they all have such high preset pressures & waste so much gas - there has been ample discussion already on limiting this effect through the use of small bore pipe of the shortest possible length from bottle to machine or moving the flow gauge to the front of the machine - I however have always used a normal pressure adjustable gauge with a ball type flow gauge either fixed directly on or on the machine front if practical - in use open the needle valve of the flow gauge completely with the pressure regulator unscrewed - gently increase pressure till you have about 10 > 15 % more flow than needed - now trim down with the needle valve to get exact flow required - when the flow is stopped by the machines solonoid valve the pressure will only increase very slightly & the resulting surge on next use will be very small - I also think using a 2stage regulator is a good thing to maintain good consistent gas flow regardless of cylinder pressure. ![]()
