Page 5 - ADDENDUM - The 4230 flow meter will become inaccurate displaying the depth, flow, and total flow when exposed to electromagnetic fields in excess of 1.0V/m between 105 MgHz and 820 MgHz. It is suggested that the instrument be placed in a location where these electromagnetic fields are not present, or the source of the radiation is removed from the vicinity of the instrument if possible.

Page 16: Description
The 4230 uses the bubbler method of level measurement. The flow meter is normally used with some type of primary mea- suring device to measure flow in an open channel. The 4230 has built-in standard level-to-flow conversions, that cover the vast majority of open channel flow measurement situations.
Page 17: Operating Principles
1.3.1 Operation of the The bubbler system, used by the 4230 to sense level in the flow Bubbler System stream, works as follows: A small compressor pumps air into a reservoir.

4230 Flow Meter Section 2 Programming 2.1 Getting Started You must program the 4230 Flow Meter to accurately monitor a flow stream. The 4230 will usually also need a primary mea- suring device, a structure placed across a stream that regulates flow.

Page 32: Flow Conversion Type
2.5.2 Flow Conversion Type Step 2, Flow Conversion Type, determines how the flow meter calculates flow rate and total flow. For the 4230, flow rate is cal- culated by knowing the measured level and (usually) the charac- teristics of a structure called a primary measuring device.
Page 33 19th-century Irish civil engineer. There is no primary measuring device as such. Instead the pipe, with considerations for its slope and internal roughness, serves as the primary device. The 4230 Flow Meter can calculate flow in round pipes, rectangular, U-shaped, or trapezoidal channels based on this formula.

For some applications, metallic bubble line extensions may be Extensions helpful. Isco offers both stainless steel and copper bubble line extensions. The stainless steel tube may be easier to install in the flow stream than the plastic bubble line because of its rel- ative rigidity.

3.6 Flow Metering Inserts Flow metering inserts are available for use with the 4230 Flow Meter that you can temporarily install inside round pipe sewers and flow streams to create a primary device inside the pipe.

The following sections describe connecting the 4230 to Isco and non-Isco samplers. Sampler One of the uses of the 4230 Flow Meter is to control a sampler in a flow-paced sampling mode. Flow-paced sampling means that the flow meter signals the sampler to take a sample after a certain volume of flow has passed through the flow stream, rather than after a particular period of time.

The mounting rings are held in place by the outward force of spring pressure in the smaller sizes and by a screw arrangement in the larger sizes.
Page 121 4230 Flow Meter Section 4 Optional Equipment but Isco recommends facing upstream, as there is a stop on the sensor carrier that is not effective when the probe is facing downstream. • Remember to unscrew the rubber guard cap from the sensing end of the probe when you install it, or the probe will be unable to sense the flow stream.

Page 123: How The D.o. Probe Works
• Frequent maintenance is necessary when the probe is installed in flows with high grease or solids content. Tests conducted by Isco with probes installed in various waste streams have indicated that greases and solids quickly coat the probe's membrane, making it impos- sible for oxygen to enter the reaction chamber.
Page 124: Probe Preparation
4230 Flow Meter Section 4 Optional Equipment As the oxygen partial pressure varies, both the oxygen diffusion through the membrane and the probe current change propor- tionally. 4.9.2 Probe Preparation The following describes how to prepare a new probe for use, or how to change membranes on an existing probe.

4230 Flow Meter Section 4 Optional Equipment 4.9.3 Membrane Isco supplies a 2 mil (.002") thick membrane for use with the Thicknesses D.O. probe. This membrane is recommended for long-term moni- toring situations only, typical of our users' applications. Use only this thickness of membrane with D.O.

Page 140: Desiccators
5.2 Desiccators The 4230 has a reusable desiccant canister held by a steel clamp on the inside of the case lid. There is also a tubular desiccant car- tridge on the top of the case next to the connectors. The canister contains silica gel that adsorbs moisture trapped inside the flow meter's case when it is closed.
