The OMEGA® Series FLR-1600A and
FLV-4600A series flowmeters and
controllers use two of the best studied
physical properties of liquids
to measure flow: Pressure and
Viscosity. Differential pressure measurement, across a laminar flow
element, results in a flow meter that is inherently linear. OMEGA® flow
meters measure differential pressure within that laminar region
to achieve a turndown of 50:1 typical and the accuracy is ±2.0% of
full scale. It uses the same technology as the laminar gas mass
flow and volumetric flow meters, FMA-1600A and FLV-1600A. There
are no moving parts to wear out.
The FLR-1600A Series is a Volumetric Water Flowmeter. The
unique method of flow detection allows the meter to measure
extremely low flow rates at an affordable price. The FLR-1600A
Series was designed with deionized water in mind. These flowmeters are
available in ranges of 500 microliters per minute full scale to 10
liters per minute full scale.
The FLR-1600A water meter provides data on the flow rate and temperature via the standard local display and the RS232 serial output. An optional gauge pressure sensor is available on the secondary output model "-P".
The FLV-4600A Series Water Flow Controller utilizes a proportional
valve coupled to a flowmeter body creating a unique in-situ closed-loop
flow controller system. Measurements are taken within the
laminar region of the flow meter and the integral PID controller positions
the valve according to the flow set points. The controllers can accept
an RS-232 or the 0-5 Volt control input signal depending on what is
preferred. Independent of the set point voltages, the controllers can
be configured for single or dual output of the same or different
voltages and/or different parameters such as temperature
and flow. This is possible because of our laminar flowmeter design that
incorporates solid-state Differential and Temperature Sensors on the standard model to determine flow in an inherently linear system. An optional , an Absolute Gauge Pressure Sensor is available on the "-P" secondary output models.
The result is a fast responding linear flow meter with multiple
outputs. All these parameters are simultaneously visible with our
dynamic display that includes a push button operator interface.
Water flow controllers are available from 50 milliliters per minute full
scale to 500 milliliters per minute full scale.

Comes complete with 24 Vdc universal power supply, 1.8m (6') cable, 8-pin male Mini-DIN connector, operator's manual, and NIST certificate.
††Portable versions "-B" have an integral battery compartment and come complete with 24 Vdc universal power supply, 1.8m (6') cable, 8-pin male Mini-Din connector, operator's manual, NIST certificate and 9V battery installed. Portable version is not available on models with 4 to 20 mA output.
Calibrations done at ambient (21°C/70°F) temperature only.
To replace the standard RS232 communications with RS485, add suffix "-RS485" to model number, add $120 to price.
**Optional secondary output are scaled the same as the primary output scale: For alternate Temperature output scale, add suffix "-T" to the model number, no additional cost. For alternate Pressure output scale, add suffix "-P" to the model number, add $175 to cost. NOTE: Models with secondary output for pressure include optional gauge pressure sensor.
For units scaled in CFH, add suffix "-CFH" to model number, no additional cost. Specify required range in CFH.
For totalizer option, add suffix "-TOT" to model number, add 120. to the price. Please specify resolution. This is a 6-digit cvounter. Examples: For totalzing in liters with 1/100 liter resolution, the max count would be 9999.99. For totalizing in liters with 1 liter resolution, the max count would be 999999.
For a Remote Display, add suffix "-RD-*FT" to the model number, add $210 to the price. Replace the * in the suffix with the required length in whole feet, the maximum length is 3.6576 m (12'). Please note the optimum distance in feet is between 2.7 to 3 m (9 to 10').
