Liquid Level Sensor

     
 


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.

 
 


VP 601

     
 


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.

 
 


VP 601A

     
 


The VP 601 is a fiber optic led Liquid Level Sensor with a transmitter and a receiver. Attaches to VP 601B-1 for sensing through side of a reservoir that is placed on VP 601B-1 SBS platform.

 
 


VP 601B-1

     
 


The VP 601B-1 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.

 
 
   
 
 


VP 601C

     
 


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.

 
 


VP 601D

     
 

The Tubing Pinch Valve, VP 601D-1, comes with its own power supply, controllable by plugging into Liquid level Detection System (VP 601, VP 601A and VP 601B-1). VP 601D-1 is designed to remain closed until power is switched on by Liquid Level Sensor Control Module VP 601 after receiving signal from the Liquid Level Sensor VP601A. Can be combined with a peristaltic pump or used with a reagent dispensing system such as the VP 565 Reagent Dispenser shown below.


This Pinch Valve is a two way valve to control the flow of a single tubing line. In a non-powered state, the tubing is closed by pinching. After powering the valve, the pinching is relieved and liquid is allowed to flow through the tubing.

 
 


VP 601D-1

     
 

The Tubing Pinch Valve, VP 601D-1, comes with its own power supply, controllable by plugging into Liquid level Detection System (VP 601, VP 601A and VP 601B-1). VP 601D-1 is designed to remain closed until power is switched on by Liquid Level Sensor Control Module VP 601 after receiving signal from the Liquid Level Sensor VP601A. Can be combined with a peristaltic pump or used with a reagent dispensing system such as the VP 565 Reagent Dispenser shown below.


This Pinch Valve is a three way valve to control the flow of two tubing lines. In a non-powered state, one tubing is open and the other is closed. After powering the valve, the two conditions switch.
