Description
Description
The trodeks® Series FLR-1600A andFLV-4600A series flowmeters andcontrollers use two of the best studiedphysical properties of liquidsto measure flow: Pressure andViscosity. Differential pressure measurement, across a laminar flowelement, results in a flow meter that is inherently linear. trodeks® flowmeters measure differential pressure within that laminar regionto achieve a turndown of 50:1 typical and the accuracy is ±2.0% offull scale. It uses the same technology as the laminar gas massflow and volumetric flow meters, FMA-1600A and FLV-1600A. Thereare no moving parts to wear out.
The FLR-1600A Series is a Volumetric Water Flowmeter. Theunique method of flow detection allows the meter to measureextremely low flow rates at an affordable price. The FLR-1600A Series was designed with deionized water in mind. These flowmeters areavailable in ranges of 500 microliters per minute full scale to 10liters 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 proportionalvalve coupled to a flowmeter body creating a unique in-situ closed-loopflow controller system. Measurements are taken within thelaminar region of the flow meter and the integral PID controller positionsthe valve according to the flow set points. The controllers can acceptan RS-232 or the 0-5 Volt control input signal depending on what ispreferred. Independent of the set point voltages, the controllers canbe configured for single or dual output of the same or differentvoltages and/or different parameters such as temperatureand flow. This is possible because of our laminar flowmeter design thatincorporates 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 multipleoutputs. All these parameters are simultaneously visible with ourdynamic display that includes a push button operator interface.Water flow controllers are available from 50 milliliters per minute fullscale to 500 milliliters per minute full scale.
