Product
Totalizer (pulse input)
-
Two independent scalable pulse-input channels. Count up or down to a preset at rated up to 1 MHz. Scaled rate and total from the same electronic counter. Scaling for direct readout in engineering units, such as gallons or cubic feet based on counts from a turbine flow meter. One channel can display total while other displays rate.

Product
Process Meter & Totalizer
-
User-scalable for display to 999,999 for 0-1 mA, 4-20 mA, or 0-10 V process signals requiring zero and span adjustment. Ideal as flow rate meter or flow totalizer for analog flow meter signals. Includes 5, 10, 24 V transducer excitation output (user-selectable).

Product
Model QLS 4-20 mA Loop Splitter / Retransmitter
-
Generates up to four individually grounded and individually adjustable 4-20 mA loops from a single 4-20 mA or 0-10V input. Overcomes problems which occur when the same 4-20 mA signal is applied to multiple loads in series. Allows outputs to have different grounds, and allows individual loops to be opened without affecting signal to other loads.
-
Product
Process Totalizer (analog input)
-
Displays and totalizes 0-1 mA, 4-20 mA, or 0-10 V process signals. Square root extraction is standard for flow applications, allowing display of volume from the 4-20 mA signal of a flow transducer with a linear or squared output.
-
Product
Phase Angle Meter
-
Exceptionally fast response (up to 20 updates per second) and high accuracy for low frequencies, such as AC line frequency. A resolution of 1, 0.1 or 0.01 is user-selectable. Accuracy is 0.01% up to 100 Hz, 0.1% at 1 kHz, and 1% at 10 kHz.

Product
Scale / Weight Meter
-
Equipped with a DC or load cell signal conditioner, this Laureate offers special firmware for scale / weighing applications: two tare functions; count by 1, 2, 5, 10, 20, 50 or 100; auto-zero function; setpoint offset, and dummy right-hand zero for display to 999,990. Built-in excitation for up to four 350-ohm load cells in parallel.
-
Product
Time Interval Meter
-
The Laureate? time interval meter can display pulse width or time delay between individual pulses to a resolution of 0.2 s. It can also display average pulse width or average time delay between multiple pulses.
-
Product
Batch Controller (analog input)
-
Same capabilities as the Laureate pulse-input batch controller, but for 0-1 mA, 4-20 mA, or 0-10 V process signals, as made possible by a built-in voltage-to-frequency (V-to-F) converter. Square root extraction is standard for use with flow meters.
-
Product
Load Cell & Microvolt Meter
-
A high-sensitivity 5-digit meter for use with load cells, strain gauges and microvolt input signals where high accuracy and stability are required. Load cell operation allows 4- or 6-wire hookup and display in engineering units, such as lbs, kg or psi. Built-in excitation for up to four 350-ohm load cells in parallel.
-
Product
Duty Cycle Meter
-
Displays ON or OFF period as a percentage of total period over a programmed gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is user-selectable. Applications include monitoring modulated proportional control systems and pulse-modulated systems, such as radar, lasers or packet radio.

MAGNA Series "Large Digit" Elapsed Timers
Models TIM4 & TIM6
-
4-digit model (TIM4) with MM:SS or HH:MM display, or 6-digit model (TIM6) with HH:MM:SS display. Large-digit displays with a digit height of 2.2" (57 mm), 4.0" (102 mm), 5.7" (144 mm), 7.9" (200 mm), or 11.0" (280 mm) for long viewing distances. Optional relays and data I/O. Choice of display brightness and cases for indoor or outdoor mounting.

Product
Loop-Powered Digital Panel Meter
88-PRO
-
The 88-PRO Process Meter may be connected directly to a 4-20 mA, 10-50 mA or 1-5 mA current loop, with no need for additional power to the meter. This is because the meter is powered directly by the current loop, developing a maximum voltage drop of 2.5 V.

Product
Laureate Duty Cycle Meter
Model FRD
-
Configured display ON or OFF period as a percentage of total period over a gate time from 10 ms to 199.99 s. A resolution of 1%, 0.1% or 0.01% is selectable. Ideal for repetitive short pulses with a pulse width down to less than 1 s.
-
Product
Quadrature Position & Rate Meter
-
Accepts low-level differential or single-ended 5 V logic level quadrature signals from shaft encoders to display scaled position or scaled rate. One, two or four transitions may be counted at a maximum combined rate of 250 kHz and be mathematically scaled to display in engineering units from -999,999 to +999,999. An analog output scaled to the display and relay outputs are optional.

Modbus or Laurel ASCII ProtocolSerial Output DIN Rail Transmitters
-
Laureate TM Series serial output transmitters can be jumpered for two signal levels: RS232 or RS485. Two serial protocols are selectable in software: Modbus or Laurel's Custom ASCII.Modbus protocol operation is fully compliant with the Modbus Over Serial Line Specification V1.0 (2002) for 2-wire, half-duplex connection.
