1.0 Introduction
The Bulkslide flow meter measures the flow rate of gravimetrically fed bulk solids and should only be used for free-flowing, non-
adhesive bulk solids. The Bulkslide flow meter can be used for mixing, blending or ratio control applications in petrochemical,
agricultural, aggregate, food and pharmaceutical industries.
This manual describes the safe and correct use in all phases of operation.
Manuals and additional resources are available from the Rice Lake Weighing Systems website at www.ricelake.com

2.0 Installation
Installation procedures generally should be a combination of the end user’s best engineering practices in compliance with local
codes and the manufacturer’s recommendations. To achieve maximum performance, the following precautions should be observed.
Failure to heed the following statements could result in severe injury or death.
Take all necessary safety precautions when installing the scale carriage including wearing safety shoes,
protective eye wear and using the proper tools.
Always turn off the power supply before any connection is made or removed.
Before welding, the power supply must be off and the connectors removed.
Failure to heed the following statements could result equipment damage and void the warranty.
2.1 Unpacking
Immediately after unpacking, visually inspect the bulkslide to ensure all components are included and undamaged. The
shipping crate should contain the unit and an installation manual. If any parts were damaged in shipments, notify Rice Lake
Weighing Systems and the shipper immediately.
2.2 Lifting
Care must be taken when lifting the bulkslide to its location. Use the following tips to safely lift the unit.
Death or crushed limbs caused by goods falling while being transported.
• Transport the Bulkslide at designated lifting points (Figure 2-1)
• Select the correct lifting gear for the weight being transported
• Do not stand under suspended loads
• Secure the transport route
Improper transport can cause damage to the load cell.
• Transport the Bulkslide without vibration if possible
• Set down the Bulkslide as gently as possible

2.3 Storage
When not in use, store the Bulkslide in it’s original packaging, making sure that the area where the unit is kept is;
• Dry
• Frost free
• Vibration free
2.4 Bulkslide Parts
Figure 2-2. Bulkslide Component Parts
2.5 Checking the Operating Conditions
The following tips should be checked when operating the Bulkslide unit.
• The surface must be level within  degree
• Install option customer feeder if necessary
• Must be sufficient clearance to open the housing doors toward the inside of the meter
• Must be sufficient clearance to be able to open the rear sensor cover for maintenance

2.6 Installing the Bulkslide
Use the following steps to install the Bulkslide feeder.
1. Fix the discharge flange to the material feeder.
2. Establish the material supply using the Master feeder or the customer feeder.
3. Make sure that the support structure is free from vibration.
Welding currents can damage the load cell so weld with extreme caution making sure that no welding current flows
through the flow volume meter.
Strong vibrations can influence measured values so provide a sufficient mechancial support structure and secure
the mounting structure if necessary.
2.7 Connecting Electronics
Several things must be done when wiring up the electronics.
• Use a shielded connecting line between the Bulkslide and the load cell, the power output 0 (4) - 20 mA and between
relay contacts
• The shielding connection and the connector lines is connected to protective earth conductor connected to the terminal
strip
• A proper, low impedance protective earth conductor is installed
• Lines in the clamp area should be laid as far as possible without any crossover
2.8 Compressed Air Cleaning System Connections (Optional)
If compressed air is present on site, it can also be hooked up. This is the customer’s responsibility. Connect compressed air and
solenoid valve in accordance to wiring diagrams (customer supplied).

3.0 Operation (Feeder Types)
There are various arrangements for planning the material supply to be fed to the feeder. The arrangement depends on the
application that product is being used for. The following sections show different arrangements.
There must be optimum conditions for measuring product.
• Bulk material must be dry and cannot solidify or stick
• Bulk material flows with steady throughput and at a low speed
• Bulk material flows in a purely vertical direction without impact
• No air flow must be present

3.4 Direct Drop From a Silo/Container
Figure 3-1. Direct Drop Type
The opening on the feeder gate must be no wider than half the straight unimpeded inflow section (Figure 3-1, #A) on a direct
drop from a silo or container. A larger opening can result in overload and damage to the meter. Make sure that material does not
hit the feeder slide and make sure that there is never a backlog as these forces can result in overload and damage to the meter.
3.5 Customer Feeders
The feeders shown in Figure 3-2 are also appropriate measure that can be used to feed the product stream evenly.

4.0 Maintenance
4.1 Inspection
Inspect the Bulkslide every six months for contamination and clean if necessary. Depending on the application, inspection might
be sooner or later, depending on plant maintenance procedures.
Calibrate the unit every six months. Depending on the application, calibration might be sooner or later, depending on plant
maintenance procedures.
4.2 Cleaning
Use the following recommendations when cleaning the Bulkslide unit.
• Clean the outer service using a dry brush
• Carefully clean the inside of the unit
• Remove all dust deposits with a vacuum cleaner if possible
• When cleaning with water, make sure that the measuring slide is completely dried after cleaning.
4.3 Dismantle and Transport
If the Bulkslide unit is to be moved to another location, use the following steps to dismantle the unit.
1. Disconnect all electronics.
2. Disconnect the secondary feeder material feeder.
3. Dismantle the material feeder.
4. Transport the Bulkslide without vibration is possible.
