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.

True AC RMS Panel Meter
The Laureate? True RMS meter offers a high accuracy 4 1/2 digit display for five voltage ranges and four current ranges. It is suited for AC applications where there is considerable distortion of current waveforms from nonlinear loading. The input is AC coupled to read only the AC component, such as ripple on a power supply.

2", 4", 6", 8" or 11" Large-Digit Displays
Grand Series
Available with 57 mm (2.2"), 102 mm (4.0"), 144 mm (5.7"), 200 mm (7.9"), or 280 mm (11.0") digit height for clock, timer, totalizer, frequency and rate inputs. RS-422 and dual-relay output options.

Batch Controller (pulse input)
A low-cost controller for repetitive fill operations. The typical application utilizes a flow meter input and two built-in relays: a Prewarn relay slows down the pump near a preset to avoid overshoot and a Batch relay stops the pump at the preset.

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
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.

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.

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.

Frequency, Rate Meter, Flow Rate Indicator
Two independent scalable pulse-input channels from 0 Hz to 1 MHz. Channels may be combined arithmetically. One channel can display total while other displays rate. High read rate for control applications: AC line frequency can be measured to 50.0000 or 60.0000 Hz in a few line cycles. Ideal for use as a tachometer or readout of a turbine flow meter.

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.
