The Laureate Model FRT is a UL-listed, 6-digit panel meter which can simultaneously track rate and totalized rate from the same pulse input. The display can be toggled between rate and total at the push of front panel key or external switch. When used with a turbine flow meter, the unit can display rate in units of flow, such as GPM, or totalized flow in units of volume, such as Gallons.

To determine rate, the Laureate FRT first calculates frequency by timing the period between pulses with crystal accuracy, and then multiplies this frequency by a user-programmed scale factor.

The Laureate FRT can also display rate and totals for non-flow applications that utilize a sensor with a pulse output. For example, the unit can display linear speed by timing pulses from a proximity switch, and display total length by integrating these pulses. For rate measurements, the pulse rate can be from 0.05 Hz to 1 MHz.

The Laureate FRT can operate with a wide range of pulse inputs. Exceptional flexibility is provided by the unit's universal dual-channel signal conditioner, which accepts magnetic signals from 12 mV to 250 Vac as well as signals from proximity switches with a PNP or NPN output, TTL or CMOS logic, and contact closures. Jumper selections provide optimum operation for different sensor types and noise conditions.

A built-in isolated 5, 10, or 24 Vdc excitation supply is standard to power proximity switches and other sensors. Options include dual relays for control or alarm, isolated 4-20 mA and 0-10V analog outputs, and an RS232 or RS485 port for data communications with a host computer or PLC. Modbus RS485 is fully supported.

The base price is $270. For more information and pricing of options, visit www.laurels.com/frequency.htm
