Ideal for batching, industrial process control, mobile hydraulic euipment and computerPLC- controlled hydraulic system monitoring applications.

FOR 1/" – 2" PIPE SIZES STYLER

SIMPLE TO INSTALL RUGGED AND RELIABLE All transmitters are factory calibrated and shipfully assembled. Simply install the transmitter into your system and apply power. Without delicate internal components to break,abrade or corrode, the Lake flow transmitter will provide many years of low-maintenance service. INDUSTRY STANDARD OUTPUTS COMPATIBLE WITH LAE MONITORSRT AND R FLOW ANALYERS Transmitters provide proportional analog outputsof 4-20mA, 0-5 dc and -5 dc, 20-2000 Hz square-wave pulse. These outputs will drive popular data acquisition devices, meters and analog input cards. DIRECT READING All transmitters provide a visual indication offlow rate integral to the transmitted output. The Lake flow rate transmitter combines withthese Lake analyzers to make a powerful flow instrument capable of remote monitoring of rate and total flows. WEATHER-TIGHT CONSTRUCTION The rugged cast aluminum NEMA type 4 enclosure allows installation in outdoor applica- tions and in environments where liquid tight seals are required.

The -5dc output requires an external 24 ohm resistornot included with transmitter to be wired at the receivingdevice. ENGINEERING SPECIFICATION THE IN-LINE FLOW RATE MONITOR/ TRANSMITTER SHALL: ? Be factory calibrated for 4-20mA, 0-5dc, -5dc, and square wave pulse outputs. ? Use the variable annular orifice technique with compression spring recoil. ? Not require inlet or outlet straight plumbing, or require vertical orientation. ? Have a measuring accuracy of ±2.5% of full scale in the center third of the measuring range, and ±4% in upper and lower thirds. ? Have a stainless steel sharp-edged orifice ? Have a maximum working pressure rating of500 or 6000 PSIG for liquids. ? Have a maximum working pressure rating of 600 or 000 PSIG for gasses. ? Have a weather-tight external construction. ?
