WARNING The 4210 Flow Meter has not been approved for use in “hazardous locations” as defined by the National Electrical Code.
Page 87 Noise – Background noise can interfere with the operation of the flow meter. You must filter this noise out, or the flow meter may trigger on noise rather than the echo. The 4210 uses a tuned circuit to filter unwanted noise outside the operating frequency.
Page 88: Accessories
Wavelength – You can determine the wavelength of sound by dividing the velocity of the sound by the frequency. The fre- quency of the 4210 is about 40 kHz. The length of a 40 kHz sound wave is found by dividing 1,125 by 40,000 which is 0.02815 feet or 0.3378 inches.

The potential, when read by a sensitive voltmeter, translates into a reading of pH. With an Isco flow meter, the voltage is sent first to a preamplifier inside the probe to reduce the impedance of the circuit and improve the signal-to-noise ratio, and then on to the parameter module to allow greater operating distance from the flow meter.
Page 112: Ph Probe Installation Guidelines
4210 Flow Meter Section 4 Optional Equipment Flow streams with a high grease content will coat the sensing surfaces of the probe quickly, clogging them and slowing the response time or stopping it altogether. Installation in very greasy flow streams is not recommended.
Page 113 For horizontal mounting, the probe fastens to a sensor carrier that snap-fits to an Isco mounting ring. The mounting rings fit various diameters of round pipes 15" diameter and smaller. For larger pipes, use the Isco Scissors Ring. For installation details, refer to the instruction sheet supplied with the mounting ring.

• Frequent maintenance is necessary when the probe is installed in flows with grease or solids content. Tests conducted by Isco with probes installed in various waste streams indicate that grease and solids quickly coat the probe's membrane, making it impossible for oxygen to enter the reaction chamber.
