Unlike the LDL100, the design of the LDL2x0 requires the fluid to flow through the measuring channel. This minimises the influence of turbulence. Note that the LDL is not recommended for installation in pipe cross-sections smaller than 2 because the measuring channel does not reach the flow through the pipe. Most commercially available clamp T-pieces have a neck that prevents the measuring channel from reaching the flow. If you wish to use a T-piece or socket fitting, please install the LDL201. The latter is designed for such applications due to its greater immersion depth.
