Mounting
Mount the control housing to a secure surface with screws or bolts. To gain access to the mounting holes, remove the front cover. The mounting holes are directly under the front cover screws. The primary element is supplied with a foot bracket, which can be attached to a secure surface. Alternatively, the unit can be supported by the piping and the foot bracket can be removed.

CAUTION:
Although this meter has an empty pipe detection function, under certain conditions of empty pipe or partially-full pipe the meter may read a flow when there is none. If this is a hazardous condition, mount the meter in such a way as to ensure the meter will always be full of liquid.

Connections
The unit ships with the coil activation and signal leads already connected to the control box. To connect output signal or alarm relay leads, remove the front cover. See Connections diagram. Power connection uses a standard power cord. If conduit connection is required, remove the cord and strain relief hole for a conduit connector.

Grounding
For proper operation, one or both of the ground lugs must be well connected to a good quality earth ground. (The ground lugs also retain the foot bracket). See grounding diagram.

Display
The flow rate is displayed in the time and volume units which have been selected (liters/min, for example). The cumulative total flow is displayed in the chosen units, up to eight(8) digits. It then resets to zero and begins again.

Outputs
The analog output which has been chosen varies continuously with the flow. If the output is too "jumpy" (changes too frequently), it can be damped either by increasing the average time (see "Fast Analog Output" setting) or by selecting "Disabled" under Fast Analog Output and increasing the amount of damping using the Low Pass Filter setting.

The pulse output will produce a 50% duty cycle pulse at the volume intervals for which it is set (one pulse per liter, for example). Note that since each pulse consists of equal times on and off, if the interval between pulses is large the pulse may retain in the "on" condition for several seconds.

The relay alarm output will only energize if the flow goes above (high) or below (low) the flow alarm setting. The alarm relay will remain energized until the flow exceeds the setpoint by 5% (hysteresis).
See Specifications.
This is the power-up display. Press SET to begin programming.
Rate/Total display (shows two(2) seconds after power-up).
Use the UP key to choose the volume unit: milliliters (mL) liters(L) or gallons (G).
Use the UP key to choose the time base for rate: per second (S) per minute (M) per hour (H) per day (D).
Use the UP key to choose number of decimals places: 0, 0.0, 0.00
Leave this unchanged unless you intend to use the 0-5 V output. Standard setting is for 4-20 mA. Consult factory for 0-5 V output.
Leave this unchanged unless you have a demanding closed-loop application. Standard setting is "diabled". If you enable this output, use the UP key to select a response time, 50 to 1000 millisecond. This will control how rapidly the analog output tracks flow.
Use the LEFT and UP key to set the percentage of full scale at which peak analog output (20 mA or 5 V) occurs. On a max 10 gpm meter, 60% would be 6 gpm, for instance.
Use the LEFT and UP key to set the percentage of full scale at which the high flow alarm will energize. On a 10 gpm meter, 90& would equal 9 gpm, for instance.
Use the LEFT and UP key to set the percentage of full scale at which the low flow alarm will energize. On a 10 gpm meter, 10& would equal 1 gpm, for instance.
Use the LEFT and UP key to set the number of pulses (0000 to 9999) per unit. If you have selected liters, it will be pulses per liter, etc.
This setting controls the smooth/responsive tradeoff of the display. Increasing the time makes the display more smooth, but slower to respond to change. Use the UP key to set. When using the meter with pulsing flows, it may be necessary to increase the time. Choice: 1, 2, 5, 10, 20 seconds.
Use the UP key if you wish to enable the totalizer reset. It will switch between "Enabled" and "Disabled". If the reset in enabled, every time the UP key is pressed (during normal operation) the totalizer will reset to zero.
Settings finished, wait five(5) seconds to return to normal operations.
