We are currently measuring the drum level on high pressure steam boilers 168Bar 560C using DP cels with constant head chambers. We use density compensators to compensate for the changes in level due to pressure changes. We need to update our system and need new analogue density compensators. I know that Siemens made a unit some years ago which accepted DP and pressure inputs but does anyone now know of such a product? Don't want to use computer (PC) system.
