The V&P Liquid Level Sensor can be used with most reagent reservoirs to
maintain the amount of liquid in the reservoir. The sensor is small and
non-intrusive and is easily attached to the side of a reservoir. Once the
sensor detects the absence or presence of a liquid it will trigger a signal.
This signal then activates a pinch valve, peristaltic pump, or any other
flow restriction device to automatically refill the reservoir to maintain a
desired liquid volume. |

The Liquid Level Sensor Control Module, VP 601, includes the
following features: amplifier, AC-out control, current
loop control and power supply. The amplifier has a long
connector cable to allow for easy placement within the
dispensing setup. |

The VP 601 is a fiber optic led Liquid Level Sensor with a
transmitter and a receiver.
Attaches to VP 601B for sensing through side of a reservoir
that is placed on VP 601B SBS platform.

The VP 601B is the SBS Mounting System for positioning the
Liquid Level Sensor, VP 601A, next to a reservoir. The
reservoir is placed on the SBS platform with the Liquid
Level Sensor either on the side or the end of the
reservoir. The height of the Liquid Level Sensor can be
adjusted to produce the desired liquid volume.

The VP 601C is an optional connector for when a peristaltic
pump is used to move liquid into reservoir. It is a DB15
control connector for Barnant Corp. model Masterflex
#7550-20 peristaltic pump. |

The Tubing Pinch Valve, VP 601D, comes with its own power
supply, controllable by plugging into system composed of VP
601, VP 601A and VP 601B. Can be combined with a
peristaltic pump or used with a reagent dispensing system
such as the
VP 565 Reagent Dispenser shown below. |

Demonstration of how the Liquid Level Sensor System can be set up with the
V&P Reagent Dispenser,
VP 565, to control the flow of liquid into a
VP 756CM-P Bubble Paddle Mixing Reservoir using the
VP 601D Tubing Pinch Valve.
The VP 601D tubing pinch valve is turned on and off by a signal from
the amplifier (part of VP 601) as shown in the photos to the right.
