6 5700 BULK TANK GAUGE WITH 1/2“ cONNEcTIONS LIQUID LEVEL GAUGES 5700 anD 17000 series GaUGe speciFicati ons The armored design o the gage oers maximm protection or the sight tbe rom mechanical impact. Three sides o the gage are protected with a metal rame, while the ace o the gage is protected with an impact resistant polycarbonate shield. This shield can be cstom calibrated to read tank volme or any other desired calibration. Please see page 1 2 or standard shield calibration options. A wide variety o wetted materials and seals are available to ensre compatibility with whatever fid is being sed. For monting prposes, a monting lg is welded to the back o the gage. The 5700 series has 1/2” MNPT x 3/8” FNPT threaded process connections. 1/2” to 2” fanged process connections are also available. The standard sight tbe is 5/8” O.D. glass. Other sight tbe options are also available pon reqest. The 17000 gage is tted with 1” MNPT process connections (fanged process connections are also available). The standard sight tbe is 1” O.D. glass, which makes it ideal or viscos liqids. special GaUGe applica tion - cheMical injection systeMs 5700 and 17000 gages are sed to calibrate chemical injection systems. The injection rate o a chemical metering pmp is checked by closing a valve between the gage and the chemical storage tank and observing the change in fid height in one minte. using the rate scale on the ront o the shield, cont the nmber o marks the fid level passed dring the one minte test period. This will give yo the actal chemical pmp rate. I the rate is not the one desired, make an adjstment to the chemical pmp eed rate, and condct as many one minte tests as is necessary to set the chemical pmp to the rate desired. 5700 Bulk Tank Gauge with Optional Flange Connection The 5700 and 17000 series gauges are armored liquid level gauges with NPT or fanged onnetions at eah end. These gauges provide a visual means or heking the ontents o a bulk tank. They an also be used to set and monitor the injetion rate o a hemial metering pump. The gauges operate in low to medium pressure appliations up to 500 psig. 17000 BULK TANK GAUGE WITH 1“ cONNEcTIONS
