Model 302i field-mounted totalizer/rate indicator requires no external power and can be configured as intrinsically safe for use in hazardous areas. It can operate with turbine and positive-displacement flowmeters. By measuring the time interval between input pulses, it calculates flow rate and provides a stable and accurate 4-20 mA output for low frequency inputs. Technical bulletin offers a list of features and a general description of the indicator. Physical characteristics and dimensional drawings are also provided.
