Section 1 Introduction

Table 1-2 Technical Specifications for the 4220 Flow Meter (Continued)

	Flowlink Data Storage and Retrieval System
Memory Partitions		Maximum of 6 user-defined memory partitions for level or event stor-
		age.
Data Storage		Rate of data storage user-selected in 1, 2, 5, 10, 15, 30, 60, or 120
		minute intervals.
Baud Rates		Serial connection - 300, 1200, 2400, 4800, or 9600 baud.
		Serial connection with the optional internal modem - 2400 baud.
Storage		80,000 bytes, apportioned per reading as follows: flow = 4 bytes,
		level = 2 bytes, sample = 4 bytes, pH or D. O. = 1 byte)
Level Data		Level readings are stored as a 16-bit number representing .1mm
		(0.0394 inch); effective range is 0–65279 meters.
		Flow Conversion

Flow Rate Calculations

The flow meter creates a table of level-versus-flow rate from program selections; this table divides the level span into 256 equally-spaced level increments. Each level increment corresponds to a specific flow rate. During data collection, if the measured level falls between two table values, the flow meter will perform a linear interpolation to calcu- late the flow rate value.
