| Flow
Rate Transmitters and Sensors |
|
|
 |
| • |
Simple
to Install: All
transmitters are factory calibrated and ship fully assembled.
Simply install the transmitter into your system and
apply power. |
| • |
Weather-Tight
Construction: The
sealed, corrosion resistant, enclosure allows installation
in environments where liquid tight seals are required.
|
| • |
Industry
Standard Outputs: Transmitters
provide proportional analog outputs of 4-20mA, 0-1mA,
0-5Vdc and 1-5 Vdc1. These outputs will drive
popular data acquisition devices, meters and analog
input cards. |
|
| • |
Rugged
and Reliable: Without
delicate internal components to break, abrade or corrode,
the Lake flow transmitter will provide many years of
low maintenance service. |
| • |
Direct
Reading or Optional Digital Display: All
transmitters provide a visual indication of flow rate
integral to the transmitted output. For improved readability,
an integral digital display is available. |
| • |
Compatible
With Lake Monitor's R100 & R/T100: The
Lake flow rate transmitter and analyzer combine to make
a powerful flow instrument capable of monitoring rate
and total flows. |
1 The 1-5Vdc output
requires an external 250 OHM resistor to be wired at the
receiving device.

Load
Driving Capacity:
4-20mA: Load resistance is dependent on power supply
voltage. Use the following equation to calculate maximum
load resistance: Max Loop Load (ohms) = 50(Power supply
volts - 12). 0-5Vdc: Minimum load resistance 1000 ohms.
0-1mA: Maximum load resistance 100 ohms. 1-5Vdc: Minimum
load resistance 25K ohms |
