1151 type transmitter has many kinds of models which can measure micro-differential pressure to large differential pressure, low pressure to high pressure, level, vacuum and gravity. If it is matches with throttling device, it can measure flow without prescription devices. Flange level transmitter includes flat flange and insert flange. The installation includes 3＃ and 4＃、150＃（working pressure is 1.89Mpa）and 300＃（working pressure is 4.95Mpa）. In addition to 316 stainless steel-wetted materials, there is Hastelloy, Mongolia Nile and tantalum which can be used in corrosive media.

1151 type transmitter is compact with explosion-proof and all-weather structure. The installation and operation are simple. Terminals and amplification circuit can be placed in the upper chamber in the closed electrical and separated from each other. Therefore, when it is field wiring, the amp was still working under the closed state. Amplification circuit has reverse polarity protection to prevent damaging to the transmitter.
