Profile: Elster Instromet specializes in the measurement and control of natural gas. We manufacture gas measurement and control equipment. We also develop volume correctors and flow computers. These range from temperature volume correctors for commercial customers, to flow computers for stations in the fields of gas distribution and transportation. The metering and regulation product range covers devices for measuring consumption which can be used both for custody and non-custody transfer, as well as traditional gas regulators for low, medium and high pressures. KleanLine filters are designed to remove contaminants in the form of dust, dirt, rust, weld slag, and pipe scale down to a particle size of 10 or 25 microns.
