ABB Instrumentation K250 MassMeter System. Model (transmitter): 1215-A-0. S/N (transmitter): TW6093. 316 Stainless steel transmitter. Power supply: 110 V. Sensor W/Series 1210/1215 Transmitter. Model (sensor): K250. S/N (sensor): 505005. Software version 70H8(1). Pressure rating: 1800 psi. Flow rate: 250 lb/min. ABB Mass Meters allow accurate mass flow measurement of virtually all fluids, slurries, and highly viscous and multi-phase flows. Measurement is unaffected by changes in fluid temperature, pressure, viscosity, density or velocity profile. Inlets/outlets: (2) 1 in. dia. S-line fittings. Overall dimensions (sensor): 7-1/2 in. L x 7-1/2 in. W x 11-1/2 in. H. Overall dimensions (transmitter): 35 in. L x 7-3/4 in. W x 36 in. H. (ACN80a)
